AlCl3–NaI(NaBr)–t-BuOH: mild, chemo- and stereoselective reagents for hydrohalogenation of propiolic derivatives
摘要:
(Z)-beta-lodo-propenamides and -beta-iodo-propenoic esters were selectively prepared in high yields, at room temperature, through reaction of 2-propynamides and 2-propynoic esters, respectively, with AlCl3 and Nal in the presence of t-BuOH in dichloromethane. These experimental conditions are compatible with the presence of acid sensitive acetal groups. Alternative use of EtOH or H2O in place of t-BuOH was investigated. (Z)-Bromo-propenamides and corresponding esters were prepared according to a similar procedure using sodium bromide in refluxing acetonitrile. (C) 2009 Published by Elsevier Ltd.
