An unprecedented approach for the synthesis of homo- and hetero-1,2,4-triaryl benzenes has been developed using a simple base-mediated reaction of either α-aryl cinnamyl alcohols or α,γ-di-aryl propanones. The salient feature of this strategy involves the sequential hydride transfer, regiospecific condensation, regiospecific dearylation, and aromatization under metal-free reaction conditions. The synthesis of unsymmetrically substituted triphenylenes by oxidative coupling of the synthesized 1,2,4-triaryl benzenes has also been demonstrated.

β-Lithiooxyphosphonium ylides, made in situ from an aldehyde and methylenetriphenylphosphorane, react with a second aldehyde to form E-allylic alcohols. α-Branching and α,β-unsaturation in the second aldehyde, together with the lack of further substitution on the phosphorane carbon play important roles in selectivity. A range of these aldehydes, in addition to aromatic aldehydes as the second aldehyde also provided synthetically useful access to E-allylic alcohols.
Reduction of activated conjugated alkenes by the InCl3-NaBH 4 reagent system

A combination of a catalytic amount of indium (III) chloride and sodium borohydride in acetonitrile reduces selectively the carbon-carbon double bonds in conjugated alkenes such as α,α-dicyano olefins, α,β-unsaturated nitriles, cyanoesters, cyanophosphonate and dicarboxylic esters. However, reduction of chalcones is little different. They are reduced to a mixture of saturated ketones and alcohols if the reaction mixture is quenched with H2O, whereas quenching with MeOH leads to saturated alcohols only.
CYCLOPENTENONE DERIVATIVES BY SOLVOLYSIS OF 2-FURYLIDENE CARBINOLS
Antonioletti, Roberto,Mico, Antonella De,Piancatelli, Giovanni,Scettri, Arrigo,Ursini, Ornella
, p. 745 - 746 (2007/10/02)
Solvolytic treatment of 2-furylidene carbinols 1 leads to cyclopentenones 2 in satisfactory yields only under carefully chosen experimental conditions.Otherwise, a very interesting competitive process, implying the conversion of 1 into a quite different c
