Herein, we present a rapid and efficient method for synthesizing cyclicacetals and ketals utilizing a rotary evaporator. Unlike the conventional Dean–Stark dehydration process, which typically demands extended reaction times and copious amounts of organic solvents, our approach affords the synthesis of cyclicacetals and ketals with varying ring sizes in 30 min while using minimal quantities of dimethyl
