O-Demethylation of (9S,13S,14S)-3-methoxy-17-methylmorphinan-10-one (2) to (9S,13S,14S)-3-hydroxy-17-methylmorphinan-10-one (3) and reduction of 3 to 10α- and 10β-hydroxylated morphinans 4 and 5, are described. The stereochemistry of these epimeric alcohols was established on the bases of 1H nmr data.
Ö(9 -Demethylation小号,13小号,14小号)-3-甲氧基-17-甲基-10-酮(2)〜(9小号,13小号,14小号)-3-羟基-17-甲基-10-描述了一种(3)和3至10α-和10β-羟基吗啡喃4和5的还原。这些差向异构醇的立体化学是基于1 H nmr数据确定的。
