Intramolecular Michael addition reaction for the synthesis of benzylbutyrolactones.
A convenient synthesis of benzyl-gamma-butyrolactone derivatives via intramolecular Michael addition reaction of nitro-substituted aryl allyl beta-ketocarboxylates is reported. The method features simple operation, mild reaction conditions and high efficiency.
متن کاملEnantioselective Michael Addition of Water
The enantioselective Michael addition using water as both nucleophile and solvent has to date proved beyond the ability of synthetic chemists. Herein, the direct, enantioselective Michael addition of water in water to prepare important β-hydroxy carbonyl compounds using whole cells of Rhodococcus strains is described. Good yields and excellent enantioselectivities were achieved with this method...
متن کاملAmmonium monovanadate: a versatile and reusable catalyst for Friedel-Crafts alkylation and Michael addition of indoles
Ammonium monovanadate (NH4VO3) has been devoted as an efficient, commercially available, eco-friendly and reusable catalyst for the synthesis of bis(indolyl)methanes (BIMs), oxindole derivatives and also Michael adducts of indoles at 50 °C under solvent-free conditions. The reusability of this solid acid catalyst in addition with its selectivity has also been examined.

متن کاملHexafluorobenzene: a powerful solvent for a noncovalent stereoselective organocatalytic Michael addition reaction.
A dramatic enhancement of the diastereo- and enantioselectivity in the nitro-Michael addition reaction organocatalysed by a commercially available α,α-L-diaryl prolinol was disclosed when performing the reaction in unconventional hexafluorobenzene as a medium. DFT calculations were performed to clarify the origin of stereoselectivity and the role of C(6)F(6).
