are general and have been successfully applied to the high yielding preparation of other aldol adducts such as 2b and 2c. The two step transformation of (E,E) 2a into the asymmetric (Z,Z)-2-(4-cyanobenzylidene)-7-(4-iodobenzylidene)cycloheptan-1-one 5 has been optimized. The radiochemical yield for the radiolabelling of 5 with K[11CN] followed by palladium catalysis to give the labelled bisnitrile 7 was

An economical and facile synthesis of alpha,alpha'-(EE)-bis(benzylidene)-cycloalkanones was achieved by the reaction of cycloalkanones with different aromatic aldehydes using ethanolic KOH in good yields. Few of the selected compounds were reduced with NaBH4 to the respective alpha,alpha'-(EE)-bis(benzylidene)-cycloalkanols. All these compounds and our earlier synthesized cyclohexyl phenyl methanols were evaluated for their antitubercular, antifungal and antibacterial activities. Several compounds displayed moderate antitubercular activity with MIC = 12.5-1.56 mu g/mL. However, none of the compounds displayed any significant antifungal activity. (c) 2008 Elsevier Masson SAS.
