A short and stereoselective total synthesis of (±)-sesamin by radical cyclisation of an epoxide using a transition-metal radical source
Tetrahedron Letters, 2000Co-Authors: Kalyan Kumar Rana, Chandrani Guin, Subhas Chandra RoyAbstract:Abstract A short, efficient and stereoselective synthesis of a Furofuran lignan, (±)-sesamin, has been achieved in good overall yield through the radical cyclisation of an epoxide using a Ti(III) reagent as the radical initiator.

an unprecedented coii tetraphenylporphyrin catalyzed decomposition of bicyclic endoperoxides a new approach to substituted Furofuran systems
European Journal of Organic Chemistry, 2000Co-Authors: Mehmet Emin Sengul, Nermin Simsek, Metin BalciAbstract:CoII-tetraphenylporphyrin-catalyzed decomposition of bicyclic endoperoxides 4 and 5 with a strained double bond moiety has been studied. Compounds 4 and 5 have been synthesized by photooxygenation of 3 which itself was obtained by dichloroketene addition to cycloheptatriene, followed by removal of the chlorine atoms. An unusual decomposition mode of 4 promoted by CoII-TPP resulted in the formation of 8 and 9 which are important building blocks in Furofuran systems.

A new Furofuran lignan fromGeranium thunbergii Sieb. et Zucc
Archives of Pharmacal Research, 2006Co-Authors: Qing-he Liu, Ji-eun Jeong, Eun Jin Choi, Young Hee Moon, Eun-rhan WooAbstract:A new Furofuran lignan, 4-hydroxykobusin ( 3 ), together with known lignans, kobusin ( 1 ), and 7,7'-dihydroxybursherenin ( 2 ), were isolated from the whole plant of Geranium thunbergii Sieb. et Zucc (Geraniacaceae). The structures were determined based on the spectral data and a comparison with the published data. This is the first report of the presence of Furofuran lignan in Geranium species.
