pyrimidine derivatives are presented herein: 1) A catalyst-free multicomponent reaction of electron-deficient alkynes, aliphatic amines and formaldehyde and 2) Ag(I)-catalyzedsynthesis of pyrimidines from electron-deficient alkynes, anilines and formaldehyde by a dominoreaction. Under optimized conditions, the multicomponent reactions were accomplished with high regioselectivity and excellent yields. A computational
