A diastereoselective and divergent method for synthesis of a highly functionalized (Z)-fluoroalkene dipeptide isosteres has been developed. The key feature of this synthetic method is an efficient one-pot reaction involving reduction/asymmetric alkylation via transmetalation, which produces trans-amide type (Z)-fluoroalkenes flanking two stereogenic centers in high yields, with excellent (Z)-selectivity
已经开发了用于合成高度官能化的(Z)-氟代烯烃二肽等排体的非对映选择性和发散方法。该合成方法的关键特征是有效的一锅反应,涉及通过金属转移进行的还原/不对称烷基化反应,该反应可高产率地产生侧接两个立构中心的反酰胺型(Z)-氟代烯烃,并具有出色的(Z)选择性和非对映选择性。还描述了实用的基于Fmoc的固相合成特定的CXCR4拮抗假肽25,该肽含有(Z)-氟烯烃等排异构体。
