An ANRORC mechanism has also been proposed (besides an inverse cycloaddition reaction) in the conversion of 1-methylpyrimidinium iodide into 3-ethoxycarbonyl-2-methylpyridine on treatment with ethyl -amino-crotonate (95RCB1272) (Scheme 23a). The reaction starts by addition of the -carbon of the crotonate at the electron-deficient 4-position of the... [Pg.47]
