Absolute configuration of diacetylated acrenol as its chloroform solvate
Abstract
The title compound, (15S)-15,16-diacetato-3β,20-epoxy-3α-hydroxy-9-epi-7-pimaren-19,6β-olide chloroform solvate, C24H32O8·CHCl3, formed from the diacetylation of acrenol, isolated from the tubers of Humirianthera ampla, crystallizes as a chloroform solvate. The anomalous dispersion of the Cl atoms allows the absolute configuration to be determined. The structure is based on a pimarane skeleton and shows an identical conformation to the …
