Controllable synthesis of P-chiral 1,2- and 1,3-diphosphines via asymmetric Diels–Alder reactions involving functionalized allylic phosphines as dienophiles†
Abstract
Optically pure P-chiral 1,2- and 1,3-diphosphines were synthesized chemoselectively and stereoselectively from the chiral organopalladium complex promoted asymmetric Diels–Alder reaction between 3,4-dimethyl-1-phenylphosphole (DMPP) and cis- and trans-ester substituted allylic
