摘要: A process for the preparation of 1,3a,8-trimethyl-1,2,3,3a,8,8a-hexahydro-pyrrole[2,3-b]indol-5(3aS,8aR)heptylcarbamate, of formula (I)
by reacting eseroline with heptylisocyanate in the presence of a metal cyanate and of a quaternary ammonium salt, in polar aprotic solvents.摘要翻译: (I)的1,3a,8-三甲基-1,2,3,3a,8,8a-六氢 - 吡咯[2,3-b]吲哚-5(3aS,8aR)庚基氨基甲酸酯的制备方法, )通过在金属氰酸盐和季铵盐存在下在极性非质子传递溶剂中使eseroline与庚基异氰酸酯反应来制备。
