- STEREOSELECTIVE SYNTHESIS OF THE AROMATIC ANALOGS OF RETINAL AND RETONOIC ACID
-
The stereoselective synthesis of 9-aryl-4-carboxy-3,7-dimethyl-2Z,4Z,6E,8E-nonatetraenoic acids and 9-aryl-3,7-dimethyl-2Z,4E,6E,8E-nonatetraenoic acids was realized.The latter isomerize readily and with good yields under the influence of iodine additions to 9-aryl-3,7-dimethyl-2E,4E,6E,8E-nonatetraenoic acids.The transition from the isomeric 9-aryl-3,7-dimethyl-2,4,6,8-nonatetraenoic acids to the corresponding isomeric 9-aryl-3,7-dimethyl-2Z,4E,6E,8E-nonatetraenals and 9-aryl-3,7-dimethyl-2E,4E,6E,8E-nonatetraenals was realized.
