Cl. Gibson et al., A STUDY OF 4-SUBSTITUTED 5,5-DIARYL OXAZOLIDIN-2-ONES AS EFFICACIOUS CHIRAL AUXILIARIES, Tetrahedron letters, 39(37), 1998, pp. 6733-6736
A series of three 5,5-diaryl substituted oxazolidin-2-ones (diphenyl,
dinaphthyl and ditolyl) have been prepared and shown to be particularl
y effective chiral auxiliaries to afford high yields and diastereosele
ctivities for alkylation and azidations of their N-acyl derivatives. T
he 5,5-ditolyl oxazolidin-2-one proved to be particularly efficacious
in terms of diastereoselectivity, yield and solubility, (C) 1998 Elsev
