is straightforward and employs inexpensive, commercially
available donors, and very little decomposition of the gly-
cosyl bromide was observed even in the absence of molecu-
lar sieves and/or inert conditions. The commercial availabil-
ity of the glycosyl bromide makes it an attractive substrate
in certain settings where timelines can preclude lengthy syn-
theses of glycosyl donors. In addition, the ability to recycle
the molten salt and to perform the reaction at elevated tem-
peratures results in a flexible, cost-efficient glycosidation [20] V. Kumar, V. S. Parmar, S. V. Malhotra, Tetrahedron Lett. 2007,
