Abstract
A biomimetic synthesis of pallescensin A (1), a furanoid sesquiterpene of natural origin is effected by concerted cyclisation of (6E)-9-(3-furyl)-2,6-dimethylnona-2,6-diene (2). The diene (2) has also been converted into a mono-epoxide (3) and the latter cyclised stereoselectively into 3-β-hydroxypallescensin A(4) which is subsequently deoxygenated to (±)-pallescensin A.This publication has 0 references indexed in Scilit:
