6-hexahydro-8-methoxy-1H-phenalene (3a) has been prepared by two routes. One starts from 6-methoxy-α-tetralone (4a) and involves a single 3-carbon extension and cyclization of the alcohol (7b); the other starts from 3-(3-methoxyphenyl)propanoic acid (5a) and proceeds via a 4-carbon extension and a double cyclization of the diol (10).
通过两种途径制备了以前未知的甲氧基取代的苯衍
生物2,3,3a,4,5,6-六氢-8-甲氧基-1H-苯(3a)。一个是从6-甲氧基-α-四氢
萘酮(4a)开始的,涉及到一个3-碳原子的延伸和醇的环化(7b);另一个从3-(3-
甲氧基苯基)
丙酸(5a)开始,并通过4-碳延伸和二醇(10)的双环化进行。
