A Stereoselective Synthesis oftrans-1,2-Disubstituted Alkenes Based on the Condensation of Aldehydes with Metallated 1-Phenyl-1H-tetrazol-5-yl Sulfones

Abstract
The reaction of metallated 1-phenyl-1H-tetrazol-5-yl sulfones and aldehydes gives good yields and stereoselectivity of trans-1,2-disubstituted alkenes when potassium or sodium hexamethyldisilazide is used as base and 1,2-dimethoxyethane is used as solvent.
