摘要

Determination of the stereostructure of rengyol (1), a novel nonaromatic phenylethanoid natural product isolated from Forsythia suspensa, by synthetic means has been described. The Reformatsky reaction of 4-acetoxycyclohexanone with ethyl bromoaoetate afforded two isomeric acetoxy esters (5, 6) and the one (5) which has an equatorial acetoxy1 group yielded on IAH reduction a triol identified as rengyol (1). The isomer (7), obtained similarly ...
