| abstract | 1,142,715. Abscisin II. R. J. REYNOLDS TOBACCO CO. 7 July, 1967 [2 Nov., 1966], No. 31390/67. Heading C2C. 3 - Methyl - 5 - (1 - hydroxy - 4 - oxo - 2,6,6- trimethylcyclohex - 2 - en - 1 - yl) penta - cis - 2, (raws-4-dienoio acid (abscisin II) is prepared by a process which comprises oxidizing a C 1-4 alkyl ester of cis,trans-α-ionylideneacetic acid with a tertiary alkyl chromate and then hydrolysing the resultant ester. Suitably the oxidation is carried out at 60- 120‹ C. using the methyl or ethyl ester of cis, trans-α-ionylideneacetic acid. Abscisin II can be separated from its trans, trans isomer by slow crystallization from ether or benzene. α-Ionylideneacetic acid is prepared by reacting α-ionone with the reaction product of sodium hydride with trimethylphosphonoacetate |
