Abstract
Pyrrolidinone 2, pyrimido[1,2-a]benzimidazoles 3a-c and 1,2,4-triazolo[4,3-a]pyrimidine 4 are prepared by condensation of 3-trifluoroacetyl substituted lactams 1a-c with cyclic 1,3-bis-nucleophiles. The nature of the nucleophile determines whether the reaction occurs with or without lactam ring opening.
