In previous studies, it was reported that a neighbouring equatorial ester group is essential for a good yield of nitrite-mediated triflate inversion, whereas with neighbouring benzyl ether groups or axial ester groups, mixtures are generally produced. In
Regioselective benzoylation of 6-O-protected and 4,6-O-diprotected hexopyranosides as promoted by chiral and achiral ditertiary 1,2-diamines

Monobenzoylation of triols (6-O-silylated glycopyranosides) or diols (4,6-O-benzylidenated glycopyranosides) with benzoyl chloride and triethylamine at - 60° to 23° is promoted by catalytic amounts of ditertiary 1,2-diamines. The regioselectivity depends
