Synthesis of asperdiol: Synthesis of asperdiol. Still, W. Clark; Mobilio, Dominick (Dep. 7218-52-2 and 87829-31-0 are also occured in this study. Chem., Columbia Univ., New York, NY 10027, USA). J. Org. Chem., 48(24), 4785-6 (English) 1983. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) Stereoselective macrocyclization of aldehydoallylic bromide I with CrCl2 allows a convenient synthesis of the 14-membered cembranoid antitumor agent asperdiol (II). The 2 asym. centers created by the cyclization are remotely controlled (1,6-asymmetric induction) to the extent of 4:1 by the distant epoxide function to yield the 4 chiral centers of II. .
