Here, the one\u2010pot synthesis of methacrylic esters from acetone, a haloform and alcohols in the presence of an organic base is described. Using DBU as the organic base for the reaction of acetone, chloroform and methanol in acetonitrile afforded MMA in 66\u2009% yield. When the solvent was replaced by benzonitrile, the product MMA was successfully purified by distillation. Applicability of this process to various alcohols was also investigated to show ethyl, phenyl, CF\n                    <jats:sub>3<\/jats:sub>\n                    CH\n                    <jats:sub>2<\/jats:sub>\n                    , and\n                    <jats:italic>n<\/jats:italic>\n                    \u2010C\n                    <jats:sub>6<\/jats:sub>\n                    F\n                    <jats:sub>13<\/jats:sub>\n                    CH\n                    <jats:sub>2<\/jats:sub>\n                    CH\n                    <jats:sub>2<\/jats:sub>\n                    esters were obtained in moderate yields.
