  摘要：

  A variety of optically active 3-substituted cis-cyclohexane-3,5-dien-1,2-diol acetonides were readily prepared from chiral 5-(tert-butyldimethylsilyloxy)-2-cyclohexenone through a seven-step reaction in good overall yield. The synthesis also allowed preparation of the acetonide having an H-2-atom at the 5-position. (C) 2001 Elsevier Science Ltd. All rights reserved.

  The gene encoding a versatile biocatalyst that shows high enantioselectivity for a variety of ketones, SCR (Saccharomyces cerevisiae carbonyl reductase), has been identified, cloned, and expressed in Escherichia coli. Two types of expression systems with high NADPH-regenerating capacities have been constructed. One is the tandem system, where the genes encoding SCR and GDH (glucose dehydrogenase) are

  enantioselective total synthesis of (-)-zampanolide, a macrolide marine natural product with high anti-cancer activity is described. For synthesis of the 4-methylene tetrahydropyran unit of (-)-zampanolide, initially, we relied upon an oxidative C-H activation of an alkenyl ether and intramolecular cyclization to provide the substituted tetrahydropyran ring. However, this strategy was unsuccessful
