The synthesis of N-[7-(2-amino-3,4-dihydro-4-oxo-quinazolin-6-yl) -6-formyl-1-oxo-heptyl]-L-glutamic acid (2, abenzyl 10-formyl-5,8,10-trideazafolic acid) as a potential enzyme-assembled tight binding inhibitor of glycinamide ribonucleotide transformylase (GAR Tfase) or aminoimidazole carboxamide ribonucleotide transformylase (AICAR Tfase) is reported. The inhibitor was prepared by a convergent synthesis

unique reaction pathway involving aromatization-driven C–C cleavage to remove the acyl moiety, followed by Cu-mediated oxidative elimination to form an alkene between the α and β carbons. The newly adopted N′-methylpicolinohydrazonamide (MPHA) reagent is key to enable efficient cleavage of ketone C–C bonds at room temperature. Diverse alkyl- and aryl-substituted olefins, dienes, and special alkenes
