Jv. Allen et al., PREPARATION OF NOVEL SULFUR AND PHOSPHORUS-CONTAINING OXAZOLINES AS LIGANDS FOR ASYMMETRIC CATALYSIS, Tetrahedron, 50(3), 1994, pp. 799-808
The preparation of enantiomerically pure ligands which contain both an
oxazoline group and an additional sulfur or phosphorus donor atom are
described. Methylthiomethyl, o-thioanisyl and thienyl oxazolines have
been prepared in one step, and o-diphenylphosphinophenyl oxazolines h
ave been prepared in two steps in good yields from commercially availa
ble starling materials.
