Reactions of heterocyclic ketene aminals with activated carbonylcompounds are strongly influenced by the structure of the heterocycle moiety. Six-membered heterocyclic ketene aminals with or without an N-methyl group such as 3 and 4 underwent efficient addition and consecutive cyclocondensationreactions with diethyl oxomalonate 9 to produce γ-lactam-fused pyrimidine derivatives 10 and 11 in moderate
