Abstract
ABSTRACT
Microwave irradiation of a mixture from 3-carboxy-4-[phenyl- or (4-methoxyphenyl)]-3-butenoic acid (2a or b), 2-[phenyl- or (4-methoxyphenyl)]methylenebutanedioic anhydride (3a or b) or methyl 3-carboxy-4-[phenyl- or (4-methoxyphenyl)-]-3-butenoate (4a or b) with different hydrazines, aliphatic or aromatic amines in 1000 watt-microwave oven at 30-80% of its power for 2-20 minutes gives 1,2-bis(3-carboxy-4-phenyl-3-butenoyl)hydrazine (8), 2-(4-methoxyphenyl)methylenebutane- dioic hydarzide (9), N-substituted-3-carboxy-4-aryl-3-buten- amides (5, 12-16, 18, 20, 22, 24, 26, 28, 30, 32 and 34), N-substituted-2-arylmethylenebutanimides (6, 7, 10, 11, 13, 17, 19, 21, 23, 25, 27, 29, 31, 33 and 35) in excellent yields and high purity.
The structures were assigned in accordance to their elemental analysis and spectral data; IR, 1HNMR and MS.
