Paragraph 0104; 0105, (2017/01/02)
PROBLEM TO BE SOLVED: To provide an N-vinylimidazolidone compound polymer that is expected to be applied for a cell culture material, a temperature-responsive material and others. SOLUTION: The present invention provides a polymer polymerized with an N-vinylimidazolidone compound (1) as a monomer, or a copolymer comprising the monomer and a monomer of a different structure (R1 is H, C1-12 alkyl or acyl; R2 and R3 is H or methyl).

(Chemical Equation Presented) New isoxazolidines were synthesized in good to excellent yields by 1,3-dipolar cycloaddition of N-vinylamide dipolarophiles and nitrones. Strikingly, solvent-free conditions gave high conversion and yields, shortened reaction time, and minimized degradation products. N-Vinyloxazolidin-2-one and its analogues used in these cycloaddition reactions were conveniently prepared in excellent yields by a modified version of Buchwald's one-step copper-catalyzed vinylation using vinyl bromide. From the adducts, a two-step access to various unsymmetric aspartate derivatives was also described.
