(5R)-Ethyl 6-benzyl-8,8-dimethyl-7,9-dioxo-1-oxa-2,6-diazaspiro[4.4]non-2-ene-3-carboxylate

(5R)-Ethyl 6-benzyl-8,8-dimethyl-7,9-dioxo-1-oxa-2,6-diazaspiro[4.4]non-2-ene-3-carboxylate

In the title compound, C18H20N2O5, the pyrrolidine ring adopts an envelope conformation with the C atom bonded to the methyl groups as the flap. The dihydroisoxazole ring is essentially planar (r.m.s. deviation = 0.041&#8197;&#197;) and forms a dihedral angle of 65.19&#8197;(...
