A set of rhenium-catalyzed arylation–acyl cyclizations between (hetero)arylmagnesium halides and enol lactones through a cascade C(sp2)?C(sp2)/C(sp2)?C(sp2) bond formation under mild reaction conditions has been developed. Indeed, a wide range of functional groups on both organomagnesium halides and enol lactones is well tolerated by the simple rhenium catalysis, thus furnishing polyfunctionalized indenones in one-pot fashion and with complete control of the regioselectivity. Moreover, this approach also provides a straightforward synthetic route to neolignan and (iso)pauciflorol F. Mechanistic studies demonstrated that the reaction involves a sequence of syn-carborhenation and intramolecular nucleophilic addition.

An efficient and facile protocol for the annulation of o-halobenzaldehyde derivatives with diverse internal alkynes has been developed using cyclopalladated ferrocenylimine as the catalyst, and the indenones as the products could be obtained in moderate t
REACTIVITY OF PHENYLIODONIUM BIS(ARYLSULPHONYL)METHYLIDES TOWARDS ALKENES AND ALKYNES: CRYSTAL STRUCTURE OF 9-PHENYLSULPHONYL-1,2,3,4,4a,9a-HEXAHYDRO-1,4-METHANOFLUORENE

Thermal or photochemical reactions of phenyliodonium bis(arylsulphonyl)methylides with alkenes lead normally to gem-(arylsulphonyl)cyclopropanes.Norbornene and trans-stilbene, however, afford 1-(phenylsulphonyl)indane derivatives.The crystal structure of the title compound /= 3.0>> confirmed the identity of the product with norbornene.Diarylacetylenes give 1-(arylsulphonyl)indenes.Thermal decomposition of the ylides involves a new rearrangement, with formation of aryl arenethiosulphonates.
