Abstract

The present invention relates to a novel process for producing a delta-lactone of the formula:using an acyl halide of the formula:wherein R<1>, R<2 >R<3 >and X are described herein, as well as novel intermediates. In particular, the present invention relates to a process for enantioselectively producing the (R)-delta-lactone.
