Expedient Route to Chalcogenophosphinates with Glucose Moieties via Todd–Atherton‐Like Coupling between Secondary Phosphine Chalcogenides and Diacetone‐d‐Glucose in the CCl4/Et3N System

Abstract

ABSTRACTSecondary phosphine chalcogenides react with diacetone‐d‐glucose (DAG) in the system CCl4/Et3N (70°C, 4–24 h) to afford DAG chalcogenophosphinates in up to 79% yield, thus paving a short way to optically active chalcogenophosphinates with glucose moieties. As an example, a mild regioselective hydrolysis (70°C, aqueous MeCOOH) of DAG bis(2‐phenylethyl)selenophosphinate) obtained leads to monoacetone‐d‐glucose bis(2‐phenylethyl)selenophosphinate.
