%X Saturated cis and trans 3,1- and 1,3-benzoxazines (1-4) reacted with chloroacetyl chlorides to yield azeto[1,2-a][3,1]- and [2,1-b][1,3]benzoxazines (5, 6, 8, 9a,b). In one case, the addition took place with partial cis-->trans inversion of the starting compound. Adduct (7), containing two condensed 1,3-oxazine rings, was also isolated. The stereostructures of the new compounds were proved by H-1 and C-13-nmr spectroscopy, with NOE measurement data. The reaction mechanism is discussed.
