    Abstract: 1,163,777. Formylmethylene-oxazolidinones. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Nov., 1966 [25 Nov., 1965], No. 52635/66. Heading C2C. [Also in Division C4] Compounds of the formula wherein R, R 1 and R 2 each denotes an aliphatic, cycloaliphatic, araliphatic or aromatic radical with up to twelve carbon atoms, R 1 and R 2 may also denote joint members of a 5- to 12- membered cycloaliphatic ring and R 1 may also be H and preparation thereof by reacting a compound of the formula wherein R, B 1 and R 2 have the above significance with a compound of the formula wherein R 3 and R 4 each denotes C 1 -C 4 alkyl radical or a C 6 -C 10 aryl radical or R 3 and R 4 together with the nitrogen atom which they substitute and, if desired, with another hetero atom may form a heterocyclic ring having preferably 5 or 6 members at a temperature of 0‹ to 120‹ C. in an inert solvent such as a hydrocarbon, chlorohydrocarbon or ether with boiling point between 40‹ and 200‹ C. and subsequently hydrolysing the product in a conventional manner by treating it with specified alkaline agents. The formamido chlorides of the third general formula above are prepared by treating an appropriate N-formylamino compound with a specified inorganic acid chloride, in particular, those derived from dimethylformamide, N- formylpiperidine and N-methylformanilide are used in the examples. The preparation of 3- phenyl-, 3-cyclohexyl- and 3-n-butyl-substituted 5 ,5-dimethyl - 4-formylmethylene-oxazol - idin-2-one; 3-cyclohexyl- and 3-n-butyl-substituted 5,5 - pentamethylene - 4 - formylmethylene - oxazolidin - 2 - one; and 3 - benzyl and 3-(3 1 -methoxypropyl)-substituted 5- methyl - 5-ethyl - -4-formylmethylene - oxazolidin- 2-one is described.
