H. Heath et al., New methods for the synthesis of P-chirogenic diphosphines: An applicationto the development of an improved asymmetric variation of the Rh(I)catalyzed [4+2] cycloaddition, SYNTHESIS-S, (15), 2001, pp. 2341-2347
A series of new P-chirogenic diphosphines has been prepared by efficient an
d complementary synthetic procedures. The utilization of a series of these
bidentate ligands possessing steric linker variations and a conserved P-chi
rogenic domain in an asymmetric variation of the Rh(I)-catalyzed [4 + 2] en
ediene cycloaddition is described.
