Methyl 7-keto-1,2,3,4,4a,5,6,7-octahydronaphthoate (Va) has been prepared by the reduction of 7-methoxy-1,2,3,4-tetrahydronaphthoic acid (III) with lithium and ammonia followed by hydrolysis of the enol ether, esterification and migration of the double bond. Alkylation of Va has led to the substitution at the expected 8-position. Methyl 4-keto-7-methoxy-1,2,3,4-tetrahydronaphthoate (X), an intermediate
7-酮-1,2,3,4,4a,5,6,7-八氢萘甲酸甲酯(Va)通过将7-甲氧基-1,2,3,4-四氢萘甲酸(III)还原而制得锂和氨,然后烯醇醚水解,酯化和双键迁移。Va的烷基化导致在预期的8位上的取代。4-酮-7-甲氧基-1,2,3,4-四氢萘甲酸甲酯(X)是制备III的中间体,已被转化为3-甲基-3-氰基-4-氰基-4-酮-7-甲氧基的甲基-1,2,3,4-四氢萘甲酸(XIII)。
