- W2359796412 abstract "Functionalized ketene dithioacetals are important intermediates in organic synthesis.α-Functionalization reactions based on them provide potential precursors for the construction of usefully carbo-and heterocyclic compounds.In this paper,a versatileα-bromination of functionalized ketene dithioacetals was developed.In the presence of H2 O,the reactions of functionalized ketene dithioacetals(1) with CuBr 2 in THF at room temperature gave variousα-bromo ketene dithioacetals(2) in excellent yields with high regioselectivities.The mechanism of thisα-bromination is proposed to undergo an addition of bromine formed in situ to compound 1 and sequontial elimination of theα-proton.The simplicity of execution,mild conditions,inexpensive,easily usable brominating agent and high yields,make this synthetic method attractive for practical applications." @default.
