  IBX/LiBr-promoted one-pot oxidative anti-Markownikov bromohydroxylation/bromoalkoxylation of Baylis–Hillman olefins

  摘要：

  The first example of one-pot oxidative anti-Markownikov bromohydroxylation and bromoalkoxylation of Baylis-Hillman (BH) adducts (olefins) is reported. The reaction is performed at rt using LiBr as the bromine source and 2-iodoxybenzoic acid (IBX) as the oxidant. The process involves oxidation of BH adducts with IBX to give beta-ketomethylene compounds in situ, which undergo highly regioselective vicinal functionalization with LiBr/H2O or LiBr/ROH in the same vessel to afford of alpha-bromo-beta-hydroxy or alpha-bromo-beta-alkoxy compounds, respectively, in excellent yields. The alpha-bromo-beta-hydroxy Compounds are readily transformed into epoxides in aq NaOH. (C) 2008 Elsevier Ltd. All rights reserved.

  The reaction of sodium hypochlorite with methyl 3-hydroxy-2methylenealkanoates or 3-aryl-3-hydroxy-2-methylenepropanenitriles, dispersed on silica gel, in acetonitrile leads to oxidation of the alcohol function and epoxidation of the methylene group to give 2,2-disubstituted oxiranes in good yield.
