Convergent Synthesis of Methylenomycin B via Selenium-assisted Intramolecular SN2' Cyclization

A highly convergent and efficient synthesis of methylenomycin B has been achieved by the reaction of the lithium enolate of 4-chloro-4,5-dimethyl-5-hexen-3-one with phenylselenenyl bromide followed by selenoxide elimination.

A convergent Synthesis of Methylenomycin B and Analogues Via Selenium Assisted Cyclopenta-annelation

Reaction of the lithium enolate of 4-chloro-4,5-dimethylhex-5-en-3-one 2 with benzeneselenenyl bromide at -78 deg C gives 2,3,5-trimethyl-5-phenylselenocyclopent-2-enone 3.Treatment of compound 3 with 15percent H2O2 in methylene dichloride at 0 deg C gave
