Abstract
AbstractHerein, metal triflates–catalyzed one‐pot domino cyclocondensation of 1,3‐bis‐sulfonylacetones and 3‐arylacroleins via (3+3) or (3+2+1) annulation has been proposed to construct diversified 2‐sulfonyl‐4‐arylphenols and 2,6‐bis‐sulfonyl 5‐aryl‐4‐arylidene‐2‐cyclohexenones. In this effective reaction, C−C and C=C bonds are formed via a cascade process and 3‐arylacrolein acts as a C3 and C1 synthon during the formation of a six‐membered ring system under mild conditions. A plausible mechanism has been proposed and discussed.
