Abstract
The X-ray structure of the title reaction product is 2-acetoxy-5H-pyrr olo[1,2a][3,1] benzoxazin-5-one (4a). New tautomeric forms of tetramic acid as the fixed derivatives 4 and 11 are described as well as a 1,3 -dipolar cycloaddition of 4 and a reverse Diels-Alder reaction of the hydrogenated cycloadducts 15a-c.
