Facile synthesis of novel spiro[azetidine-2,4'(1H)-isoquinoline-1',3',4(2'H)-triones]

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

Novel spirosuccinimide aldose reductase inhibitors derived from isoquinoline-1,3-diones: 2-[(4-Bromo-2-fluorophenyl)methyl]-6- fluorospiro[isoquinoline-4(1H),3'-pyrrolidine]-1,2',3,5'(2H)-tetrone and congeners. 1

The high concentrations of plasma glucose formed during diabetic hyperglycemia rapidly translate into high levels of glucose in tissues where glucose uptake is independent of insulin. In these tissues that include the lens, retina, nerve, and kidney, this
