Catalytic syntheses of polycyclic compounds based on norbornadiene in the presence of nickel catalysts

Abstract-The cycloadditions of olefins containing an electron-withdrawing substituent to norbornadiene are reported. The influence of the substituent and solvent nature on the [2+2+2]-cycloadduct yield and ste- reoselectivity is elucidated. The competitive cycloaddition of pairs of olefins to norbornadiene is discussed. Hypotheses about the structure of key intermediates of the process are considered. The consistent generalized mechanism for the cycloaddition of unsaturated compounds of various classes to norbornadiene is suggested. Pleiades Publishing, Ltd., 2010.

Asymmetric hydroformylation of deltacyclene

Deltacyclene (tetracyclo[4,3,0,02,903,7]non-4-ene was stereoselectively hydroformylated to exo-formyl-deltacyclane in the presence of rhodium and platinum catalysts. In the case of optically active bisphosphines up to 22% e.e-s were achieved.
