A Convenient Synthesis of α-Methylene-γ-butyrolactones from Allenyl Carbonyl Units Mediated by Mo(CO)6 through Intramolecular Cyclocarbonylation

A novel procedure for the synthesis of cis-fused bicyclic α-methylene-γ-butyrolactones from allenyl carbonyl functionalities via the molybdenum-mediated cyclocarbonylation is described. The use of Mo(CO)6 with DMSO to promote reaction results in an efficient and convenient protocol through the three...

Description
Summary:A novel procedure for the synthesis of cis-fused bicyclic α-methylene-γ-butyrolactones from allenyl carbonyl functionalities via the molybdenum-mediated cyclocarbonylation is described. The use of Mo(CO)6 with DMSO to promote reaction results in an efficient and convenient protocol through the three-component assembly in high yields.
