Pyrylium monolayers as amino-reactive platform

A new monolayer platform based on pyrylium has been developed which is reactive towards amine-terminated (bio)molecules. Upon reaction, a switch in fluorescence properties of the monolayer signifies successful immobilization of these molecules.

Reductive (3 + 2) Annulation of Benzils with Pyrylium Salts: Stereoselective Access to Furyl Analogues of cis-Chalcones

An unprecedented reductive (3 + 2) annulation of both symmetrical and unsymmetrical benzils with pyrylium salts mediated by P(NMe2)3 is described, leading to facile and stereoselective access to the challenging cis-chalcones decorate

A facile synthesis of 3,5,7-trisubstituted-4H-[1,2]diazepines by microwave irradiation

A novel approach for the synthesis of 3,5,7-trisubstituted-4H-[1,2] diazepine 5a-p from α,β-unsaturated 1,5-diketone 4 by the condensation of substituted acetophenones 1 with 1,3-dicarbonyl compound 3 in the presence of sodium tertiary butoxide has been described. The intermediate 4 reacts smoothly with hydrazine hydrate catalysed by PSSA in water under microwave irradiation to yield the product 5.
