Here the application of silyl enol ether moieties as efficient alkene coupling partners within cobalt-mediated intramol. Pauson-Khand reactions is reported. This cyclization strategy delivers synthetically valuable oxygenated cyclopentenone products, e.g., I, in yields of ≤93% from both ketone- and aldehyde-derived silyl enol ethers, e.g., II, incorporates both terminal and internal alkyne partners, and delivers a variety of decorated systems, including more complex tricyclic structures. Facile removal of the silyl protecting group reveals oxygenated sites for potential further elaboration. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3HPLC of Formula: 638-07-3).
Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.HPLC of Formula: 638-07-3
