商品

We are pleased to offer o-tolyl-CBS-oxazaborolidine as a 0.5 M solution in toluene for your research needs. When protonated with trifluoromethanesulfonimide, these chiral oxazaborolidines generate chiral Lewis acids, which have demonstrated great utility in the enantioselective Diels–Alder reaction.

we are pleased to offer both enatiomers of 2-methyl-CBS-oxazaborolidine as a dry reagent, in addition to our current offerings as a 1M solution in toluene.
