Diastereoselective cycloadditions of chiral homoallylic alcohols with benzonitrile oxide

Add time:09/05/2019    Source:sciencedirect.com

The first diastereoselective cycloaddition of a nitrile oxide with a homoallylic alcohol is discussed. The reaction of benzonitrile oxide with the magnesium alkoxides of chiral homoallylic alcohols has been shown to proceed with good diastereoselectivity, favoring the syn isomer of the resulting 2-isoxazoline.
