Venlafaxine: A heterocyclic antidepressant
American Journal of Health-System Pharmacy, 1994The pharmacology, pharmacokinetics, and clinical efficacy of venlafaxine hydrochloride, a new antidepressant, are described. Venlafaxine inhibits the reuptake of serotonin, norepinephrine, and, to a lesser extent, dopamine. In animal models, it does not significantly inhibit muscarinic, histaminic, or adrenergic receptor activity and does not inhibit ...

Synthesis of fused heterocycles from heterocyclic enaminones
Tetrahedron, 1999Abstract The reactivity of readily prepared heterocyclic enanminones with some doubly electrophilic reagents is described. Different classes of interesting fused heterocyclic systems are obtained from these enanminones in a single reaction.

Annual Reports Section "B" (Organic Chemistry), 2003
It has been a very active year in the arena of heterocyclic chemistry. Particular highlights include a new catalytic system for the formation of aziridines with easily removable N-protecting groups (Du Bois); two examples of catalytic asymmetric Staudinger β-lactam formation, independently reported by Fu and Lectka; the use of ynamine chemistry to ...
