چکیده
|
A number of 1,2,3,4-tetrahydropyrimidine-2-thiones 2a-d, have been synthesized using microwaveirradiation in an appreciable yield. cyclisation of 2a-c with different reagents gave thethiazolopyrimidinone derivatives 3-5. reaction of dimedone with aromatic aldehydes and thiourea usingmicrowave irradiation afforded the xanthenedione 8a,b as a major product. the prepared compounds werefully identified by spectroscopic methods.
