摘要

Abstract: A total synthesis of the Fusarium mycotoxin equisetin, in a manner that establishes its stereochemistry, is described. The key steps involve a lactonic variation of the ester enolate Claisen rearrangement and a novel construction of a 1-acyltetramic acid from an LN- methylserine derivative and a,% keto ester.
