| abstract | 1427303 2,4,6-Trioxo-tetrahydro-1,3-oxazines BAYER AG 7 March 1974 [9 March 1973] 10226/74 Heading C2C Novel compounds have the Formula III in which R<SP>1</SP> represents a hydrogen atom, an optionally branched C 1-12 alkyl group or a 5- membered or 6-membered cycloalkyl group, the alkyl groups being optionally substituted by a phenyl group which is unsubstituted or subsubstituted in one or more positions with fluorine, chlorine, bromine, a C 1-3 alkyl group or a trifluoromethyl group; or in which R<SP>1</SP> represents a phenyl or naphthyl group which is unsubstituted or substituted in one or more positions with a C 1-3 alkyl group or with a trifluoromethyl group; R<SP>2</SP> and R<SP>3</SP>, which may be identical or different, each represents a hydrogen atom, an optionally branched C 1-18 alkyl group or a 5-membered or 6-membered cycloalkyl group, the alkyl groups being optionally substituted by a phenyl group which is unsubstituted or substituted in one or more positions with fluorine, chlorine, bromine or a C 1-3 alkyl group; or in which R<SP>2</SP> and R<SP>3</SP> each independently represents a phenyl or naphthyl group, unsubstituted or substituted in one or more positions with fluorine, chlorine, bromine, alkoxy having 1 to 3 C-atoms or alkyl having 1 to 3 C-atoms; or in which R<SP>2</SP> and R<SP>3</SP> are joined together to form an alkylene bridge having from 4 to 6 C-atoms, optionally interrupted by oxygen or sulphur; and R<SP>4</SP> represents an optionally branched alkyl group containing from 1 to 6 C-atoms or a 5-membered or 6- membered cycloalkyl group, the alkyl groups being optionally substituted by a phenyl group; or R<SP>4</SP> represents a phenyl group which may be unsubstituted or substituted with fluorine, chlorine, bromine, C 1-3 alkyl, trifluoromethyl, an alkoxy group having 1 to 3 C-atoms or an NO 2 group. The oxazines of Formula III are obtained by reacting a #-amino-acrylic acid ester of Formula I wherein R represents a C 1-12 alkyl or a C 5-6 cycloalkyl group, the alkyl groups being optionally substituted by a phenyl group which in turn may be unsubstituted or substituted by F, Cl, Br or a C 1-3 alkyl group, with a bis- (halocarbonyl)-amine of Formula II wherein X represents chlorine or bromine. Preferred reaction conditions are a molar ratio of I : II of 1 : 1 to 1 : 2, a temperature of 0 to 200 C. and the presence of an inert solvent and/or an acid acceptor. Examples prepare oxazines of Formula III in which R<SP>1</SP> is CH 3 or phenyl; R<SP>2</SP> is H, CH 3 , phenyl, benzyl, p-methoxyphenyl, m-methylphenyl, 2,6-dimethylphenyl or cyclohexyl; R<SP>3</SP> is H or CH 3 ; and R<SP>4</SP> is CH 3 or phenyl. The compounds of Formula III possess fungicidal properties. |
