Microwave-assisted palladium mediated decarbonylation reaction: synthesis of eulatachromene

Microwave-assisted decarbonylation reactions were investigated using a palladium catalyst. A large number of aldehydes can be decarbonylated efficiently with lower catalyst loadings and under shorter reaction times compared to conventional heating. A successful decarbonylation led to the synthesis of natural product eulatachromene in three steps starting from easily available materials.
