Kurasawa, Yoshihisa,Moritaki, Yujiro,Takada, Atsushi

, p. 1619 - 1622 (2007/10/02)

The reaction of 3-methoxycarbonylmethylene-2-oxo-1,2,3,4-tetrahydroquinoxaline (Ia) with m-chloroperbenzoic acid gave 3-(1-hydroxy-1-methoxycarbonyl)methylene-2-oxo-1,2,3,4-tetrahydroquinoxaline and 2,3-dioxo-1,2,3,4-tetrahydroquinoxaline.The equilibrium between the tetrahydro form (Ia type) and the dihydro form (Ib type) was exhibited, together with the 1HNMR data.
