Iw. Davies et al., APPLICATION OF A RITTER-TYPE REACTION TO THE SYNTHESIS OF CHIRAL INDANE-DERIVED C-2-SYMMETRICAL BIS(OXAZOLINES), Tetrahedron letters, 37(6), 1996, pp. 813-814
Bis(oxazolines) 4, 6, 8, 9, 10, and 11 are prepared in a highly regio-
and diastereo-selective manner from dinitriles and indanediol 3 in a
Ritter-type reaction initiated by trifluoromethanesulfonic acid.
