An efficient and environmentally benign one-pot condensation of cyclic diketones, aldehydes naphthols was achieved with 1,4-diazabicyclo[2-2-2]octane supported on Amberlyst-15 as a novel catalyst, producing variety benzoxanthenones in good to excellent yields. The advantages this multicomponent reaction include the use heterogeneous solventless conditions simple methodology that is atom-economi...

1,2,3,4-Tetrahydroisoquinolines form a valuable scaffold for variety of bioactive secondary metabolites and commercial pharmaceuticals. Due to the harsh or complex conditions conventional chemical synthesis this molecular motif, alternative mild reaction pathways are in demand. Here we present an easy-to-operate chemoenzymatic one-pot process tetrahydroisoquinolines starting from benzylic alcoh...

Polymer functionalization of ordered mesoporous silicas (OMS) offer wide applications owing to their synergy properties. In this study, a new approach for polymer OMS is demonstrated by the co-condensation silica precursor and functional bearing triethoxysilane end-group in presence tailored poly (ethylene oxide)-b-polystyrene (PEO-b-PS) amphiphilic copolymer used as pore template. The novelty ...
