KF-Al2O3 catalyzed the condensations of 2-methylbenzoxazole and pyrazol-5-one with aromatic aldehydes
Sun,Yan,Han

In the presence of KF-Al2O3 as a solid base, 2-methylbenzoxazole 1 in DMF and 1-phenyl-3-methylpyrazol-5-one 2 in methanol, respectively, reacted with aromatic aldehydes to give 2-styrylbenzoxazoles 4a-f in high yields and 1-phenyl-3
Application of Phase-Transfer Catalysis to the Synthesis of Mono- and Bis-stilbenes and Styryls
Lokhande, S. B.,Rangnekar, D. W.
, p. 485 - 488 (2007/10/02)
A novel and convenient method has been developed for the synthesis of substituted stilbenes by the condensation of active methyl group in suitably substituted toluenes with aromatic aldehydes in aq. medium at room temperature using benzyltriethylammonium chloride as a phase-transfer catalyst.This method has also been applied for the preparation of heterocyclic styryls and extended to the synthesis of bis-stilbenes and bis-styryls using aromatic dialdehydes in place of monoaldehydes.A comparison of the results shows that the present method is superior to the conventional methods in many respects.

A series of 35 derivatives of 2-styrylbenzoxazole I-XXXV with methyl, chloro, hydroxy, methoxy, dimethylamino, nitro, cyano and methoxycarbonyl substituents have been prepared by reaction of substituted 2-acetamidophenol with respective benzaldehyde derivatives.
