Abstract

1,226,548. Oxazole derivatives. JOHN WYETH & BRO. Ltd. 15 May, 1968 [14 June, 1967; 16 Aug., 1967], Nos. 27382/67 and 37598/67. Heading C2C. [Also in Division A5] Novel compounds I and their acid addition salts in which R<SP>1</SP> is phenyl, halophenyl, alkylphenyl, alkoxyphenyl, nitrophenyl, haloalkylphenyl, mercaptophenyl, alkylthiophenyl, aminophenyl, dialkylaminophenyl, alkylsulphonylphenyl, naphthyl or heteroaryl; R<SP>2</SP> is H, 1-4 C alkyl, aryl or heteroaryl; and R<SP>3</SP> is a 2-6 C aliphatic carboxylic acid radical attached via a C of its aliphatic chain or an ester, amide, salt or hydroxamic acid derivative of the COOH group in said radical R<SP>3</SP>; with the provisos (a) that when R<SP>1</SP> is phenyl optionally substituted by CF 3 or up to 2 halo and when R<SP>2</SP> is 5-H, then R<SP>3</SP> has at least 2 C in a straight chain between the oxazole ring and the COOH group or its derivative and (b) that if R<SP>1</SP> is phenyl and R<SP>3</SP> is a 4-acrylic or n-propionic acid radical R<SP>2</SP> is not H; are prepared by (a) when R<SP>3</SP> and R<SP>2</SP> are in the 4- and 5-positions respectively, reacting (where R<SP>4</SP> is as R<SP>3</SP> or is convertible thereto) with R<SP>1</SP>CONH 2 ; (b) when R<SP>3</SP> and R<SP>2</SP> are in the 5- and 4-positions respectively, reacting alkyl -OOC-CH(hal)COR<SP>2</SP> in the form of an enamine with ammonia or an amine and an aroyl peroxide to give compounds V which are then cyclized; (c) when R<SP>3</SP> and R<SP>2</SP> are positioned as in (b), reacting alkyl OOC-CH(M)COR<SP>2</SP> (M is an alkali metal) with an aroyl peroxide to give compounds VI which are then cyclized in the presence of a N-donating agent to give I; (d) hydrolysis of esters to give acids; (e) hydrolysis of nitriles to amides and acids; or (f) esterification of the acids. Intermediates isolated are 4-chloromethyl-2- phenyl-oxazole, prepared from benzamide and sym-dichloroacetone; and 4-cyanomethyl-2- phenyl-oxazole, prepared from the former intermediate and NaCN.
