Abstract
A novel carbonylative cyclization for the synthesis of cis-fused bicyclic 3-methylenebutyrolactams from allene-hydrazone functionalities mediated by Mo(CO)6 with DMSO is described. Dramatic solvent effect of CH2Cl2 was observed to expedite the process to afford the cyclized products in good yields.
Key words
