[ 1 ] - Synthesis of Poly-Substituted Quinolines via Friedländer Hetero-Annulation Reaction Using Silica-Supported P2O5 under Solvent-Free Conditions
A highly efficient, simple and green solvent-free protocol for the preparation of poly-substituted quinolines via Friedländer hetero-annulation reaction between 2-aminoaryl ketones and carbonyl compounds in the presence of silica-supported P2O5 (P2O5 / SiO2) is described. In this method, the title compounds are obtained in high to exc...
[ 2 ] - 1,3-Disulfonic acid imidazolium hydrogen sulfate {[Dsim]HSO4} as a highly efficient, recyclable and green catalyst for the preparation of α,α´-bis(arylidene)cycloalkanones
A highly efficient and simple method for the preparation of α,α´-bis(arylidene)cycloalkanones under solvent-free conditions has been developed. The crossed-aldol condensation of cycloalkanones (1 eq.) with arylaldehydes (2 eq.) in the presence of 2.5 mol% of ionic liquid 1,3-disulfonic acid imidazolium hydrogen sulfate {[Dsim]HSO4} afforded the title compounds in high yields and short reaction ...
