An eco‐efficient new path of mortar pestle grinding approach for the construction of methanol and ethylthio substituted pyridines with in silico studies
A green and highly regioselective approach for the synthesis of poly-substituted new pyridine derivatives via the Knoevenagelcondensation followed by the Michaeladdition. The reaction involves intramolecular cyclization of easily obtainable reactants under environmentally and economically benign mortar pestle grinding technique. This method clearly proves that spatially hindered aldehydes also actively
