RING ENLARGEMENT OF N-HETEROCYCLES

Institute of Materia Medica, Chinese Academy of Medical Sciences, and Peking Union Medical college, Beijing 100050

Received Date: 10 February 1995

Treatment of N-cyanomethyl quaternary ammonium salts with NaH in tetrahydrofuran gave the desired ring enlargement products via the ylide.One of the products was subjected to reduction by sodium borohydride for the removal of the CN group.
