text] A flexible asymmetric approach to 5-alkyl tetramicacid derivatives is described, which is based on the use of 9 as the first synthetic equivalent to chiral nonracemic tetramicacid 5-carbanionic synthon 9b. The existence of the carbanion intermediate 9b was proven by trapping with trimethylchlorosilane. Application of the present method to the synthesis of antifungal alkaloid (+)-preussin, as well

A flexible two-step asymmetric approach to N-protected (R)-5-alkyl tetramates and (R)-5-alkyl tetramic acid derivatives is described. The method is based on the diastereoselective alkylation of (R)-phenylglycinol derived tetramates 7 and 8, which are the first synthetic equivalents to chiralnonracemic tetramate 5-carbanionic synthons A.
