Sequential Glaser reaction-diastereoselective cyclocarboxylation of propargylamines with CO2: A green catalytic access to bis-oxazolidinonedienes and their topochemical polymerization

A novel catalytic route for the direct synthesis of bis-oxazolidinonedienes from CO2 and propargylic amines is presented. An inexpensive copper catalyst promotes the Glaser coupling and a subsequent double cyclization...
