Reactions of cyclic oxalyl compounds, part 29: A simple synthesis of functionalized 1H-pyrimidines
摘要：
4-Benzoyl-5-phenylfuran-2,3-dione ( 1 ) and the semicarbazones 2 , ureas and thioureas 6 , respectively, combine with loss of water and carbondioxide yielding the 1 H -pyrimidine derivatives 3 and 7 , respectively, in moderate yields (30–75%). Hydrolysis of 3 b leads to the 1-amino-pyrimidine-2-one 4 .
