Sequential Glaser reaction – diastereoselective cyclocarboxylation of propargylamines with CO 2 : a green catalytic access to bis-oxazolidinonedienes and their topochemical polymerization

A novel catalytic route for the direct synthesis of bis-oxazolidinonedienes from CO 2 and propargylic amines is presented. An inexpensive copper catalyst promotes the Glaser coupling and a subsequent double cyclization step. The obtained diene derivatives undergo polymerization in the solid state, s...

Description
Summary:A novel catalytic route for the direct synthesis of bis-oxazolidinonedienes from CO 2 and propargylic amines is presented. An inexpensive copper catalyst promotes the Glaser coupling and a subsequent double cyclization step. The obtained diene derivatives undergo polymerization in the solid state, showcasing a rare example of spontaneous topochemical polymerization.
