Mah. Zahran et al., SYNTHESIS OF SOME PYRIMIDINES AND THEIR BENZO-DERIVATIVES VIA 6 PI-ELECTRON CYCLIZATION REACTIONS, Afinidad, 52(460), 1995, pp. 415-418
Reaction of 6-chloro-5-formyl-1,3-disubstituted uracils((1,2)) 1 with
different ylids were investigated either thermally or photochemically.
The suggested mechanism was based on 6 pi-electron cyclization reacti
ons((3,4)). The antimicrobial activity of the prepared compounds has b
een also studied.
