Jm. Quintela et al., A convenient method for the synthesis of thiopyrano[2,3-d : 6,5-d']dipyrimidine derivatives, HETEROCYCLE, 52(1), 2000, pp. 333-348
A convenient and efficient one-pot synthesis of thiopyrano[2,3-d:6,5-d']dip
yrimidine derivatives has been developed. The first solid-state structure e
lucidation of triheterocyclic system is also reported.
