A short and efficient enantioselective synthesis of yashabushidiols A and B and the β-hydroxy-δ-lactone moiety of compactin and mevinolin with high enantiomeric purity (98% ee) is described starting from commercially available materials. The strategy mainly comprises of iodine-induced intramolecular electrophilic addition of a carbonate occurring in a highly diastereoselective fashion and the Co-catalyzed
yashabushidiols A和B的一个短和高效对映选择性合成和康帕丁和洛伐他汀的具有高对映体纯度(98%ee)的β型羟基δ内酯基团被描述从市售材料开始。的策略主要包括碘诱导的分子内电子加成以高度非对映时尚和官能化的环氧化物作为手性诱导步骤的钴催化的两stereocentered水解动力学拆分发生的碳酸盐。
