Sasaki, Jun-ichi; Kobayashi, Makoto; Ibe, Yusuke; Nishino, Hiroshi published the artcile< Mn(III)-based oxidative radical ring-expansion reaction using squarate derivatives: selective synthesis of bis(butenolide)s and the acetate monomers>, Product Details of C19H34O2, the main research area is bis butenolide preparation furanone cyclopentenedione crystal structure; aryl alkyl hydroxycyclobutenone oxidative radical ring expansion cyclization.
The Mn(III)-based oxidation of phenyl- and alkyl-substituted hydroxycyclobutenones selectively produced the bis(butenolide)s or the acetate monomers via the 5-endo radical cyclization depending upon the concentration of the reaction. A similar reaction of hydroxycyclobutenones bearing an alkenyl and alkynyl substituent did not produce any bis(butenolide)s or acetate monomers, but the 5-exo and 6-endo radical cyclization products including the unsaturated group. The oxidation of the hydroxycyclobutenones having an unsaturated substituent in the presence of alkenes afforded radical coupling products during the 5-exo radical cyclization. The reaction details, structure determination of the products, and the mechanism for the formation of the products are described.
