1,1-Diphenylacetone
1,1-Diphenylacetone is an organic compound composed of a benzhydryl group and a methyl group attached to a central carbonyl group. Preparation One method is where phenylacetone is dissolved in benzene, reacted with bromine to effect an α-keto bromination and stirred for 3-6 hours. Then this mixture is slowly added to a solution of anhydrous aluminium chloride in benzene to catalyze a Friedel-Crafts alkylation. A lengthy workup of the reaction mixture ends in recrystallization of the product 1,1-diphenylacetone from petroleum ether.

3-Benzhydrylmorpholine
3-Benzhydrylmorpholine is a drug that was developed by American Home Products in the 1950s. It has stimulant and anorectic effects and is related to both pipradrol and phenmetrazine. Synthesis The Ethyl ester of β-Phenylphenylalanine ( Diphenylalanine), i.e. ethyl 2-amino-3,3-diphenylpropanoateCID:101017845 (1) is the starting material. Lithium aluminium hydride reduction of the ester to the primary alcohol gives 2-amino-3,3-diphenylpropan-1-olCID:15798949(2). Acylation of the primary amine with chloroacetyl chloride 9-04-9(3) gives 2-chloro-N-(3-hydroxy-1,1-diphenylpropan-2-yl)acetamide (4). Base catalyzed ring closure affords the lactam, i.e. 5-benzhydrylmorpholin-3-one (5). Further treatment with lithium aluminium hydride reduces the lactam function to the morpholine ring, thus 3-benzhydrylmorpholine is formed (6).

3,3-Diphenylcyclobutanamine
3,3,-Diphenylcyclobutanamine is a psychostimulant drug which was originally prepared as an antidepressant in the late 1970s. It appears to inhibit the reuptake of serotonin, norepinephrine, and dopamine, and may also induce their release Release may refer to: * Art release, the public distribution of an artistic production, such as a film, album, or song * Legal release, a legal instrument * News release, a communication directed at the news media * Release (ISUP), a code to i ... as well. The ''N''- methyl and ''N'',''N''-dimethyl analogues of the compound are also known and are more potent. All three agents produce locomotor stimulation in animal studies, with the tertiary amine being the strongest.

Desoxypipradrol
Desoxypipradrol, also known as 2-diphenylmethylpiperidine (2-DPMP), is a drug developed by Ciba in the 1950s which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI). Chemistry Desoxypipradrol is closely related on a structural level to the compounds methylphenidate and pipradrol, all three of which share a similar pharmacological action. Of these three piperidines, desoxypipradrol has the longest elimination half-life, as it is a highly lipophilic molecule lacking polar functional groups that are typically targeted by metabolic enzymes, giving it an extremely long duration of action when compared to most psychostimulants. Methylphenidate, on the other hand, is a short-acting compound, as it possesses a methyl-ester moiety that is easily cleaved, forming a highly polar acid group, while pipradrol is intermediate in duration, possessing a hydroxyl group which can be conjugated (e.g. with glucuronide) to increase its hydrophilicity and facilitate excretion, but no eas ...

Stimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, Mood disorder, mood, and physical activity, physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of neurotransmitter, excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the Receptor (biochemistry), receptors of excitatory neurotransmitters (e.g., nicotine) or by ...

Drug
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via insufflation (medicine), inhalation, drug injection, injection, smoking, ingestion, absorption (skin), absorption via a dermal patch, patch on the skin, suppository, or sublingual administration, dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to pharmacotherapy, treat, cure, preventive healthcare, prevent, or medical diagnosis, diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a re ...

Diphenadione
Diphenadione is a vitamin K antagonist that has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents. The chemical compound is an anti-coagulant with active half-life longer than warfarin and other synthetic 1,3-indandione anticoagulants.Meister, R.T. (ed.). 1992. Farm Chemicals Handbook '92. Meister Publishing Company, Willoughby, OH. It is toxic to mammals, in all forms; exposure and oral ingestion of the toxin may cause irregular heartbeat and major maladies associated with its impact on blood clotting, depending on dose.Bell Laboratories, Inc. July, 1990. Diphacinone Technical: MSDS. Bell Labs, Madison, WI. As a "second-generation" anticoagulant, diphenadione is more toxic than the first generation compounds (e.g., warfarin). For purposes of treating toxicity on exposure, diphenadione is grouped with other vitamin K antagonists (coumarins and indandiones); despite being directed at rodents and being judged as less ha ...

Methamphetamines
Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational or performance-enhancing drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder (ADHD). It has also been researched as a potential treatment for traumatic brain injury. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. ''Methamphetamine'' properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving its potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy such as Adderall an ...
