The elusive 4-methyl-3,4-dihydro-2H-[1,4]oxazine (2,3-dehydro-N-methylmorpholine, DNMM, 5) was confirmed to occur as degradation product of N-methylmorpholine-N-oxide (1) by trapping with the α-tocopherol-derived ortho-quinone methide in a hetero-Diels-Alder reaction with inverse electron demand. The regioselectivity of the addition was in good agreement with DFT computational data. An authentic sample of 5 was synthesized from formmorpholide (16) via 2-methoxy-formmorpholide in 38% overall yield.

The invention relates to an olefin functionalized IPr.HCl monomer, a preparation method thereof, a method for preparing an N-heterocyclic carbene functionalized organic polymer (PS-IPr-x) by using the olefin functionalized IPr.HCl monomer, and application of the N-heterocyclic carbene functionalized organic polymer as a heterogeneous catalyst for catalyzing reduction N-formylation of carbon dioxide and amine. A heterogeneous catalyst is prepared by using cheap and easily available DVB as a polymerization cross-linking agent through an AIBN-initiated olefin polymerization method, and has the advantages of low preparation cost and simple preparation method. Meanwhile, the catalytic activity of the catalyst is obviously higher than that of reported catalysts, and the catalyst has a wide practical application prospect.
