Enantiomerically pure (R)-methylphenylvinylphosphine and the P-chiral dipho
sphine ligands (5R,7R)-, (5R,7S)- and (SS,7R)-[5-(methylphenylphosphino)-2,
3-dimethyl-7-phenyl-7-phosphabicyclo[2.2.1]hept-2-ene] were stereospecifica
lly obtained in high yields from the chiral palladium template controlled D
iels-Alder reaction between (+/-)-methylphenylphosphine and 3,4-dimethylphe
nylphosphole. (C) 1999 Elsevier Science Ltd. All rights reserved.
