Abstract
A stereoselective synthesis of (1R,2R,5S)-2-benzyloxymethyl-3-azabicyclo[3.2.0]heptan-2-one was achieved, by intramolecular [2+2]-cycloaddition of (R)-vinylglycinol-derived N-allyl-b-N-keteniminium salts, with high facial diastereoselection. The regio- and stereochemical courses have been qualitatively investigated by Molecular Mechanics calculations.File in questo prodotto:
