3-Ethynylpyrrolo[2,3-d]pyrimidines are chemical intermediates for antineoplastic N-(acyl)glutamic acid derivatives. A typical embodiment is 3-ethynyl-4-hydroxy-6-pivaloylaminopyrrolo[2,3-d]pyrimidine.

Pyrrolo(2,3-d)pyrimidines

N-(Acyl)glutamic acid derivatives in which the acyl group is substituted with 4-hydroxypyrrolo[2,3-d]-pyrimidin-3-yl group are antineoplastic agents. A typical embodiment is N-{5-[2-(4-hydroxy-6-aminopyrrolo[2,3-d]pyrimidin-3-yl)ethyl]thien-2-ylcar bonyl}-L-glutamic acid.

N-(6-Amino-(pyrrolo(2,3-d)pyrimidin-3-ylacyl) )-glutamic acid derivatives

N-(Acyl)glutamic acid derivatives in which the acyl group is substituted with 4-hydroxypyrrolo[2,3-d]pyrimidin-3-yl group are antineoplastic agents. A typical embodiment is N-[4-(2-{4-hydroxypyrrolo[2,3-d]pyrimidin-3-yl}ethyl)benzoyl]-L-glutamic acid.
