The use of 3-alkenoate as a masked synthon of 4-oxo-2-alkenoate was established by a three step conversion of 3-nonenoate into 4-oxo-2-nonenoate through epoxidation, isomerization to an allyl silyl ether, and oxidation in a high overall yield. This method was applied to the short step synthesis of pyrenophorin from 7-oxo-3-octenoic acid.
使用 3-烯酸酯作为 4-氧代-2-烯酸酯的掩蔽合成子是通过三步将 3-壬烯酸酯转化为 4-氧代-2-壬烯酸酯通过环氧化、异构化为烯丙基甲硅烷基醚和氧化总产量高。该方法用于从 7-oxo-3-octenoic 酸短步合成 pyrenophorin。
