report a new class of glycosyldonors, benzoxazolyl imidates, for chemical glycosylation. The O-benzoxazolyl (OBox) leaving group was designed with an aim to compare the relative reactivity and stability of similarly structured S-benzoxazolyl (SBox) glycosides (thioimidates) developed in our lab and glycosyl trichloroacetimidates (TCAI, O-imidates) developed by Schmidt. Novel OBox donors can be activated
