SYNTHESIS AND CYCLIZATION OF N-(4-PHENOXYPHENYL)-β-ALANINES
Keywords:
arylidene hydrazides, dihydropyrimidinediones, N-substituted β-alanines, 4-carboxy-2-pyrrolidinonesAbstract
We have used the reaction of 4-aminodiphenyl ester with acrylic, methacrylic, crotonic, and itaconic acids to synthesize N-substituted β-alanines, which undergo ring closure to form derivatives of dihydropyrimidinedione and 4-carboxy-2-pyrrolidinone. We have studied the reactions of acylation and recyclization of the dihydropyrimidinedione ring, and we have synthesized derivatives of 4-carboxy-1-(4-phenoxyphenyl)-2-pyrrolidinone: arylidene hydrazides, 2[(2-oxo-4-pyrrolidinyl-1-(4-phenoxy-phenyl)]benzimidazole.
