| abstract | 1388834 Cyclic acetal derivatives SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 25 May 1972 [27 May 1971] 17564/71 Addition to 1293546 Heading C2C Novel cyclic acetal derivatives having one or other of the isomeric formulµ where R 1 is a hydroxy or alkoxy group or a group of formula -NHZ, where Z is a hydrogen atom, an alkyl, cycloalkyl or benzyl group, a phenyl-substituted amino group, or a phenyl group optionally substituted by one or more halogen atoms, alkyl groups or alkoxy groups; R 2 is hydrogen or an alkyl group; R 3 is an alkyl group; and R 4 is an aralkyl group are used as herbicides. Compounds where R 1 is alkoxy may be prepared by reacting an alkyl ester of an α-oxo carboxylic acid of formula R 2 COCOR 1 , or non-cyclic acetal thereof, with the appropriate substituted propane diol, in the presence of an anhydrous acid catalyst. Compounds where R 1 is hydroxy may be prepared by saponifying the corresponding derivative where R 1 is alkoxy. Compounds where R 1 is -NHZ may be prepared by reacting the corresponding compound where R 1 is an appropriate alkoxy or acyloxy with a compound of formula NH 2 Z. Compounds where R 1 is phenylamino may be prepared by reacting the corresponding compound where R 1 is hydroxy with phenylphosphazoanilides. |
