Ethyl Bromopyruvate

Four cinchona alkaloid-silyl ether derivatives have been used to catalyze the asymmetric “interrupted” Feist-Bénary reaction of ethyl bromopyruvate/substituted bromo-ketoesters and 1,3-Cyclohexadione. The corresponding hydroxydihydrofurans have been obtained in excellent yields (85-96%) with high enantiomeric excess (ee) values of up to 90%.

Some hitherto unreported thiazolo[3,4- a]quinoxaline derivatives have been synthesised in excellent yields via a one-pot, three-component reaction of benzene-1,2-diamines, ethyl bromopyruvate and aryl isothiocyanates in MeCN, for the first time. The protocol avoids the use of any catalysts or chromatographic separations and provides a wide range of novel thiazolo[3,4- a]quinoxalines.

Ethyl Bromopyruvate

The catalyst-free multicomponent reaction of 1,2-diaminobenzene, dialkyl acetylenedicarboxylates, and ethyl bromopyruvate forms pyrrolo[1,2-a]quinoxaline derivatives in good yields. Ethylenediamine also reacts under similar conditions to produce new pyrrolo[1,2-a]pyrazine derivatives.
