In this report, enantiomericallypure 4-trichloromethyl-2-oxetanone is shown to be a versatile aminoacid synthon leading to a variety of gamma-substituted alpha-amino acid precursors. The utility of this methodology was demonstrated by the concise synthesis of a protected homoserine equivalent, alpha-azidobutyro lactone, and a naturally occurring alpha-amino acidfrom the seeds of Blighia unijugata
