Regiospecifically generated tosylhydrazone dianions are trapped with aldehydes and ketones yielding i; l-hydrox-ytosylhydrazone dianions. Neutralization affords 6- hydroxytosylhydrazones, which may be converted with or without isolation cleanly and in good yield to homoallylic alcohols upon treatment with alkyllithium reagents. A ra-tionale is provided for the regiochemistry of this elimination. All attempts to obtain@-hydroxy ...
