Synthesis, Characterization, Crystal Structure and Biological Study of Carboxamides Obtained from 2-Aminothiazole Derivatives

Abstract: Two series of novel thiazolylcarboxamide derivatives were synthesized by the reaction of ethyl 2-amino-4-methylthiazole-5-carboxylate or 1-(2-amino-4-methylthiazol-5-yl)ethan-1-one with four substituted carbonyl chlorides at 0?°C in excellent yi

Synthesis of various cyclopropyl methyl bromide and its derivatives from ketones and/or aldehydes and some β-dicarbonyl compounds in the presence of BrCN and Et3N

The ultimate goal in this paper has been developed for the synthesis of structurally various bromomethyl cyclopropane via an α-bromoketone and/or aldehydes with ethyl cyanoacetate or malononitrile and cyanogen bromide (BrCN) in the presence of Et3N to give products in excellent yields within about 3?s. All structures were characterized by IR, 1H-NMR, 13C-NMR, and Mass spectroscopy techniques. The reaction mechanism was discussed.
