Abstract

(Chemical Equation Presented) Treatment of β-keto esters with terminal acetylenes in the presence of a catalytic amount of a manganese complex, MnBr(CO) ₅, and molecular sieves, gave multisubstituted aromatic compounds in good to excellent yields. This reaction employs [2 + 2 + 2] cycloaddition of β-keto esters and 2 equiv of terminal acetylenes with dehydration. In the case of a 1,3-diketone, the corresponding acetophenone derivative and its deacylated compound can be synthesized selectively.
