α-Thioketo-ester (6) derived from Bunte salt (5) has been shown to undergo a hetero Diels-Alder reaction with a variety of dienes to form the basis of a concise synthesis of dihydrothiopyran analogues of the potassium channel activator aprikalim.

Ethyl α-bromoesters (1)-(5) (ABr) were prepared through NBS bromination of (6)-(10) (AH) respectively.Controlled potential electrolysis of (1)-(5), dissolved in dry dimethylformamide (DMF) containing Et4NClO4 (0.1 M) allows the corresponding succinates (1
1-Aryl-3-azabicyclohexanes, a New Series of Nonnarcotic Analgesic Agents

A series of 1-aryl-3-azabicyclohexanes was synthesized by hydride reduction of 1-arylcyclopropanedicarboximides.Hydroxyphenyl analogues 20, 22, and 24 were prepared by EtSNa-DMF ether cleavage of the corresponding methoxyphenyl analogues 2m, 2n, and 23, respectively, with the secondary amines 20 and 22 going through the N-formyl intermediates 19 and 21.The p-ethoxy analogue 26 was obtained by O-ethylation of 19, followed by base hydrolysis of the amide 25.The greatest analgesic potency in mouse writhing and rat paw-pain assays was observed for para-substituted compounds.Bicifadine, 1-(4-methylphenyl)-3-azabicyclohexane (2b), was the most potent member of the series and is presently undergoing clinical trials in man.Analgesic activity of 2b is limited to the (+) enantiomer 2v, which has the 1R,5S absolute configuration as determined by single-crystal X-ray analysis.The N-methyl analogue (27d) of 2b showed significant analgesic potency, whereas the N-allyl (27a), N-(cyclopropylmethyl) (27b), and N-(n-hexyl) (27c) analogues were inactive.Bicifadine (2b) showed a nonnarcotic profile different from analogous azabicycloalkane and 3-phenylpyrrolidine analgesics.
