Heterocycles , 2010, 81 (3), 611-623
Alkylation of 4,6-dimethyl-2- and 2,6-dimethyl-4-pyrimidineacetonitrile with chloroacetyl anilides gave 4-(4,6-dimethyl-2-pyrimidinyl)- and 4-(2,6-dimethyl-4-pyrimidinyl)-5-amino-2,3-dihydro-1-arylpyrrol-2-ones, resp. Corresponding isomeric compds., 5-amino-4-pyrimidinyl-2,3-dihydropyrrol-3-ones were obtained by Claisen condensation of the mentioned pyrimidineacetonitriles with N-Boc-α-amino acid imidazolides, followed by removal of the protecting group, accompanied by simultaneous ring closure.
