The preparation of racemic 3-hydroxy-N-methyl-6-oxomorphinan (5) by acid-catalysed cyclization of 1-(4-hydroxybenzyl)-1,2,3,4,5,8-hexahydro-6-methoxy-2-methylisoquinoline (4) and its 4′-methyl ether 6 is described. The corresponding N-formyl derivatives did not give the desired cyclization.
通过酸催化1-(4-羟基苄基)-1,2,3,4,5,8-六氢-6-甲氧基-的环化反应制备外消旋3-羟基-N-甲基-6-氧代吗啡喃(5)描述了2-甲基异喹啉(4)及其4'-甲基醚6。相应的N-甲酰基衍生物没有给出所需的环化作用。
