H. Tye et al., SYNTHESIS AND APPLICATIONS OF A NEW CLASS OF PHOSPHORUS DONOR LIGANDSFOR ASYMMETRIC CATALYSIS, Chemical communications, (11), 1997, pp. 1053-1054
The synthesis and applications to allylic substitutions of a range of
novel ligands based on diazaphospholidines is described; enantiomeric
excesses of up to 89% were achieved in an allylic substitution reactio
