✦ Synopsis

Quassiols A were synthesized enantioselectively by using baker's yeast reduction and asymmetric dihydroxylation, but their optical properties were not identical to that of natural quassiol A. Stereostructure of natural quassiol A was proposed.

The title compound, C~22~H~28~O~8~, was prepared from the natural diterpenoid macrocalyxin J by two steps. It is built up from five fused rings: three six-membered rings and two five-membered rings. Two molecules are present in the asymmetric unit; both independent molecules have the same absolute c
