Facile synthesis of novel spiro[azetidine-2,4'(1H)-isoquinoline-1',3',4(2'H)-triones]
Malamas
, p. 565 - 568 (1994)
A convenient general method for the synthesis of a new heterocycle, spiro[azetidine-2,4'(1'H)-isoquinoline-1',3',4(2'H)-trione] is described. The key intermediate 2 was prepared by direct halogenation of position-4 of acid 3 with thionyl chloride, and sub
