摘要：

The transformation of 1-hydroxy-5-methoxtetralin into 4-hydroxy-8-methoxy-1-tetralone was accomplished in three steps (benzoylation, oxidation and alkaline hydrolysis). Treatment of the corresponding ketotosylate with sodium iodide and zinc dust in dimethoxyethane yielded the 8-methoxy-1-tetralone in 22% yield. The ketotosylate also underwent detosylation with sodium cyanoborohydride but afforded tetraol in 45% yield which on oxidation was converted into the required tetralone in 87% yield.
