  Identification of a Set of Genes Involved in the Formation of the Substrate for the Incorporation of the Unusual “Glycolate” Chain Extension Unit in Ansamitocin Biosynthesis

  摘要：

  The unusual "glycolate" extender unit at C-9/C-10 of ansamitocin is not derived from 2-hydroxymalonyl-CoA or 2-methoxymalonyl-CoA, as demonstrated by feeding experiments with the corresponding 1-13C-labeled N-acetylcysteamine thioesters but is formed from an acyl carrier protein (ACP)-bound substrate, possibly 2-methoxymalonyl-ACP, elaborated by enzymes encoded by a subcluster of five genes, asm12-17, from the ansamitocin bisosynthetic gene cluster.

• Lewis Base Activation of Lewis Acids: Catalytic, Enantioselective Addition of Glycolate-Derived Silyl Ketene Acetals to Aldehydes
  作者：Scott E. Denmark、Won-jin Chung

  DOI：10.1021/jo8006539

  日期：2008.6.1

  A catalytic system involving silicon tetrachloride and a chiral, Lewis basic bisphosphoramide catalyst is effective for the addition of glycolate-derived silyl ketene acetals to aldehydes. It was found that the sense of diastereoselectivity could be modulated by changing the size of the substituents on the silyl ketene acetals. In general, the trimethylsilyl ketene acetals derived from methyl glycolates
