A novel process is disclosed for the preparation of 3-pyrrolidinol compounds selected from the group having the formula: ##STR1## wherein: R is selected from hydrogen, loweralkyl, loweralkenyl, cycloalkyl, cycloalkyl-loweralkyl, phenyl-loweralkyl and substituted phenyl-loweralkyl; R.sup.1, R.sup.2, and R.sup.3 are selected from hydrogen, loweralkyl, and loweralkenyl; and the optical isomers thereof. In the process, 4-amino-3-hydroxybutyronitriles are reductively cyclized with Raney nickel to produce the 3-pyrrolidinol compound.
揭示了一种制备3-
吡咯烷醇化合物的新工艺,所述化合物选自以下结构式的组:##STR1##其中:R选择氢,低碳基,低烯基,环烷基,环烷基-低碳基,苯基-低碳基和取代苯基-低碳基;R.sup.1,R.sup.2和R.sup.3选择氢,低碳基和低烯基;以及其光学异构体。在该工艺中,4-
氨基-
3-羟基丁腈经过Raney
镍的还原环化反应,产生3-
吡咯烷醇化合物。
