The trisubstituted cyclohexenone 12, generated through a palladium-catalyzed Ullmann cross-coupling reaction between o-iodonitrobenzene and a 4,5-trans-disubstituted 2-iodo-2-cyclohexen-1-one, engaged in a tandem reductive cyclization process upon exposur
Palladium-catalyzed oxidation of cyclohexanones to conjugated enones using molecular oxygen

Oxidation of cyclohexanones into conjugated enones with molecular oxygen as oxidant was achieved by palladium catalysts. A catalyst system consists of 1 mol % Pd(OCOCF3)2 and 5,5′-dimethyl-2,2′-bipyridine accomplished maximum 84% yield for the oxidation of cyclohexanone and 51-78% yields for 4-substituted-cyclohexanones.
Intermediates for the synthesis of indole alkaloids. Synthesis of tetrahydrocarbazole derivatives
Erguen,Bayraktar,Patir,Okay
, p. 11 - 14 (2007/10/03)
The synthesis of new precursors 8 and 15 for the synthesis of tetracyclic indole alkaloids were described. Many new intermediates 4-7 and 9-14 have also been synthesized.
1,5-DICARBONYL COMPOUNDS A GENERAL PREPARATION METHOD
Duhamel, P.,Hennequin, L.,Poirier, J. M.,Tavel, G.,Vottero, C.
, p. 4777 - 4786 (2007/10/02)
In this report, a general method for the preparation of 1,5-dicarbonyl compounds and six membered ring annelation is described.This method involves the reaction of hemiacetal vinylogs 1 with enol ethers 2 or 3 in the presence of a Lewis acid.This reaction was successfully applied to the enol ethers of α and α,α'-hindered ketones such as 2,2,6-trimethyl cyclohexanone. α-Cyperone and 6-epi-α-cyperone were obtained using this process.
ALKALI METAL-HEXAMETHYLPHOSPHORAMIDE REDUCTION. PART V. REDUCTION OF SOME MONO- AND DIALKYLANISOLES BY LITHIUM IN HMPA
Kotlarek, Wojciech
, p. 809 - 815 (2007/10/02)
o-, m- and p-Alkylanisoles have been reduced.To extend our observations some dialkylanisoles have been reduced, too.In most cases results comparable with those in Birch reduction have been obtained.
