商品

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.

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.
