Octandrenolone (1) was prepared in high yield by condensation of 2', 4',6'-trihydroxyacetophenone with 3-chloro-3-methylbut-1-yne in the presence of a catalytic amount of copper(I) iodide. Methylation of 1 afforded O-methyloctandrenolone (2). Oxidation of 2 with m-chloroperoxybenzoic acid followed by hydrolysis gave the racemic trans-(+)-1-(9,10-dihydro-9,10-dihydroxy-5-methoxy-2,2,8, 8-tetramethyl-2H
在催化量的碘化铜(I)存在下,将2',4',6'-三羟基苯乙酮与3-氯-3-甲基丁-1-炔进行缩合,可高产率制备辛烯酮(1)。1的甲基化得到O-甲基辛二烯酮(2)。用间氯过氧苯甲酸氧化2,然后水解,得到外消旋的反式-(+)-1-(9,10-二氢-9,10-二羟基-5-甲氧基-2,2,8,8-四甲基-2H ,8H-苯并[1,2-b:3,4-b']双吡喃-6-基)乙酮(3),证实了先前从Mericope erromangensis分离的天然产物的结构。
