It has been shown that synthetic (–)-3-hydroxy-N-methyl-morphinane (I) possesses the same steric configuration at the C-atoms 9, 13 and 14 as the natural mor-phine alkaloids, since it can be degraded to the known (–)-cis- [2-methyl-carboxy-cyclohexyl-(l)]-acetic-acid.
已经表明,合成的(-)-3-羟基-N-甲基-
吗啡烷(I)在C原子9、13和14处具有与天然
吗啡生物碱相同的空间构型,因为它可以被降解。已知的(-)-顺式-[2-甲基-羧基-环己基-(l)]-
