A facile one-pot synthesis of tetrahydropyrimidines part 3 Synthesis of [alkanediylbis(3-alkyl/aralkyl/aryl-3,6-dihydropyrimidine-1,5(2H)-diyl)bis(arylmethanones) and [1,4-phenylenebis(3-phenyl-3,6-dihydropyrimidine-1,5(2H)-diyl)]bis(phenylmethanone)

A facile one‐pot synthetic strategy has been developed for novel [alkanediylbis(3‐alkyl/aralkyl/ aryl‐3,6‐dihydropyrimidine‐1,5(2H)‐diyl)]bis(arylmethanones) 2a‐c, 2e‐m and [1,4‐phenylenebis(3‐phenyl‐3,6‐dihydropyrimidine‐1,5(2H)‐diyl)]bis(phenylmethanone) 2d by refluxing enaminones 1a‐f in methanol with diamines and formaldehyde.
