report the chemical synthesis of Ofornine mimics from l-vasicine, structure-activity relationship studies and their in vivo screening for anti-hypertensive action in Wistar rats. It was observed that most of the analogs possessed anti-hypertensive effect; however, the duration of the effect was variable and mostly transient. The results demonstrated that the analogs 12, 13, 14, 15, and 16 showed a sharp

A totalsynthesis of the vasicinone family of natural products from bulk chemicals was developed. Reductive condensation of o-nitrobenzaldehydes with amines utilizing iron pentacarbonyl as a reducing agent followed by subsequent oxidation leads to a great variety of polycyclic nitrogen-containing heterocycles under mild conditions. Enantiomerically pure vasicinone, rutaecarpine, isaindigotone, and

The present invention relates to a facile, highly efficient and economical process for the preparation of optically active N-benzyl-3-hydroxypyrrolidine in high yield from a naturally occurring alkaloid vasicine. The natural alkaloid vasicine is used as a precursor of (S)—N-benzyl-3-hydroxypyrrolidine and (R)—N-benzyl-3-hydroxypyrrolidines which can easily be sourced from the medicinal plant Adatoda vasica by the method known in the art and transformed to optical isomers (R) and (S)—N-benzyl-3-hydroxypyrrolidine by the method described in the present invention.
