Abstract
A quick and efficient procedure for the synthesis of 5-arylmethylene-2,2-dimethyl-1,3-dioxane4,6-diones uses the condensation reaction of isopropylidene malonate and aromatic aldehydes using hexadecyltrimethylammonium bromide (HTMAB) as catalyst in water. This method provides several advantages such as neutral conditions, short reaction time, high yields, and is environmentally friendly. The isopropylidene malonate has been prepared similarly.
