Klinikai orvostan description: 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. date: 1993 type: Folyóiratcikk type: PeerReviewed format: text identifier: http://publicatio.bibl.u-szeged.hu/32167/1/aok_klny_689_93.pdf identifier: Stájer Géza; Szabó Angela E; Fülöp Ferenc; Bernáth Gábor; Sohár Pál: Structures of saturated azeto[1,2-a][3,1]- and azeto[2,1-b][1,3]benzoxazines prepared by addition of chloroacetyl chlorides to cyclohexane-condensed dihydrooxazines.
