A new pimarane-Type diterpenoid from the seeds of Bowdichia virgilioides

Abstract

A new pimarane-Type diterpenoid, sucupiol (1), and nine known furanocassane-Type diterpenoids, vouacapane (2), 7β-hydroxyvouacapane (3), 7α-Acetoxyvouacapane (4), 6α-hydroxyvouacapane (5), 6α-Acetoxyvouacapane (6), sucutinirane F (7), sucutinirane E (8), 6α, 7β-diacetoxyvouacapane (9), and 6α, 7β-diacetoxyvouacapane-14β-Al (10), were isolated from the seeds of Bowdichia virgilioides and their structures were elucidated by using 2D NMR data. The isolation of 1 provides evidence to support the presence of intermediate A in the course of biosynthesis of furanocassane-Type diterpenoids.
