Abstract

Organo-phosphorus compounds S 0080Diastereo-and Regioselective Diels-Alder Reactions of 2-Phosphaindolizines.-The reaction of substrates (I) with dienes (II) in the presence of sulfur affords the addition products with complete diastereoselectivity and with 100% regioselectivity in the case of isoprene (IIc). -(BANSAL*, R.
