Abstract
1,229,805. Naphthalene - cyclopentanone derivatives. BEECHAM GROUP Ltd. 17 March, 1969 [18 March, 1968], No. 12974/68. Heading C2C. A process for preparing compounds of the Formula I wherein R 1 is an alkyl C 1-6 radical or the group -CH 2 COOR 4 in which R 4 is a hydrogen atom or an alkyl radical, R 2 is an alkyl group and R 3 is a hydrogen atom or an alkyl C 1-6 radical comprises reacting an alkyl halide with a compound of Formula II wherein R 1 and R 3 are as defined above and X is a benzylidene, furfurylidene, group or a -CHSR 5 or -CHNR 6 R 7 radical where R 5 is an alkyl group and R 6 and R 7 are aryl or alkyl group, and thereafter removing the group X e.g. by vigorous hydrolysis by heating with NaOH in a high boiling alcohol. The compounds of Formula I wherein R 1 is the group CH 2 COOR 4 are stated to be novel. Trans - 2 - allyl - 5 - N - methylanilinoformyl- 3 - (61 - methoxy - 2<SP>1</SP>- naphthyl) - cis - 2 - methylcyclopentananone is prepared by reacting allyl bromide with 5 - N - methylanilinoformyl - 3- (6<SP>1</SP> - methoxy - 2<SP>1</SP> - naphthyl) - 2 - methylcyclopentanone. Methyl trans - 2 - allyl - 5 - N - methylanilinoformyl - 3 - (6<SP>1</SP>- methoxy - 2<SP>1</SP> - naphthyl)cyclopentanone - cis - 2 - acetate is prepared by reacting allyl bromide with methyl - 5 - N - methylanilinoformyl - 3 - (6<SP>1</SP> - methoxy - 2<SP>1</SP>- naphthyl)- cyclopentanone - 2 - acetate.
