Synthesis and substitution reactions of 4(6)-chlorodihydropyrimidines

Chlorination of the corresponding ketones with phenylphosphonic dichloride (PhPOCl2) provided ethyl 6(4)-chloro-2-methyl-4(6)-phenyl-1,4(6)- dihydropyrimidine-5-carboxylate in good yield. The cross-coupling reactions of organoboronic acids or t

SYNTHESIS OF NOVEL 1,4-, 3,4-, AND 4,5-DIHYDROPYRIMIDINES: FIRST SUCCESSFUL POCl3 CHLORINATION AND REGIOSELECTIVE ALKOXYCARBONYLATION

Chlorination of 5,6-dihydropyrimidine-4-(3H)-one derivatives (1) with POCl3 gave 1,4(3,4)-dihydropyrimidines (3), whose alkoxycarbonylation (ClCOOR-Et3N or NaH) afforded regioselectively novel compounds (4).A new Pummerer type rearrangement of compound (1
