摘要：
The first synthesis of a new zooecdysteroid gerardiasterone was achieved in a diastereoselective manner employing asymmetric dihydroxylation of the E-olefin 34 in the presence of DHQ-CLB as a chiral ligand. This synthesis unambiguously confirmed the structure of gerardiasterone as (20R,22R,23S)-2 beta,3 beta,14 alpha,20,22,23,25-heptahydroxy-5 beta-cholest-7-en-6-one (2a).
