A method for the production of delta high 3 - pyrroline, - (2) - derivatives as well as the use of delta high 3 - pyrroline, - (2) - derivatives for the production of pyrrolidone - (2) - derivatives

摘要

A method for the preparation of a substituted pyrrolidin-2-one by the hydrogenation of the corresponding 3- pyrrollin-2-one and a method for the preparation of substituted 3-pyrrolin-2- ones by the ring closure of corresponding N-aroylmethyl-acetamide. The ring closure is effected in basic media under nitrogen.
