An effective synthesis of nucleosides using glycosylchlorides as glycosyldonors in the absence of Lewis acid has been developed. Glycosylchlorides have been shown to be pivotal intermediates in the classical silyl-Hilbert-Johnson reaction. A possible mechanism that differs from the currently accepted mechanism advanced by Vorbrueggen has been proposed and verified by experiments. In practice, this
