A facile asymmetric synthesis of the octalactin lactone was developed staring from (R)-cyclohexylideneglyceraldehyde (1). The key step of the synthesis is an In-mediated diastereoselective crotylation of 1 in water, which furnished the building blocks with the required stereochemistry under operationally simple conditions. Their conversion to the appropriate intermediates, invertive esterification
从(R)-环己基亚甘油醛(1)开始发展了八actin内酯的简便不对称合成。合成的关键步骤是在水中进行1的In介导的非对映选择性crotylation ,可在操作简单的条件下为构建基块提供所需的立体化学。它们转化为合适的中间体,反相酯化反应和闭环复分解反应提供了目标化合物。
