enantioselective synthesis of the methyl ester of CPE, a potential intermediate in coronatine (COR) biosynthesis, is described. Comparison of the specific rotation of the synthetic ester with that of the methyl ester of natural CPE established that the latter possesses the (R) configuration. This configuration is the same as that found at the corresponding asymmetric center of coronatine. Structure: see
描述了CPE甲酯的首次对映选择性合成,这是冠状化合物(COR)生物合成中的潜在中间体。通过将合成酯的比旋光度与天然CPE的甲酯的旋光度进行比较,可以确定后者具有(R)构型。该构造与在冠状动脉的相应不对称中心处发现的构造相同。结构:见文字。
