Electrochemical properties of various para-substituted phenylthio-, phenylseleno-, and phenyltelluroglucopyranosides bearing acetyl, benzoyl, and benzyl protecting groups have been investigated to estimate the reactivity of chalcogenoglycosides towar

A variety of 1: 1 charge-transfer (CT) crystals were prepared by using mainly dinitrobenzoic acids (as the acceptor) and carbazoles (as the donor). Most of the CT crystals prepared from 3,5-dinitrobenzoic acid (3) and a series of N-alkylcarbazoles (1

Telluroglycosides are activated under neutral conditions and serve as excellent glycosyl donors in the glycosylation reaction. Both α- and β-anomers are selectively formed by the proper choice of the C-2 protecting group and solvent.
