I. Isaac et al., NEW AND DIRECT ACCESS TO GLYCONO-1,4-LACTONES FROM GLYCOPYRANOSES BY REGIOSELECTIVE OXIDATION AND SUBSEQUENT RING RESTRICTION, Tetrahedron letters, 36(3), 1995, pp. 383-386
Treatment of partially protected or unprotected carbohydrates with the
RhH(PPh(3))(4)-benzalacetone system leads exclusively to glycono-1,4-
lactones by regioselective oxidation and subsequent ring restriction.
