Abstract |
Halobenzoylmethylidenephosphoranes 3 are reacted under C-C bond formation to give a number of novel elongated phosphoranes 5 and 6. The C-C bond formation could be achieved both under Heck conditions ...and by metal-catalyzed ethynylation reaction. The products, desactivated phosphoranes, can be reacted in Wittig-olefinations with aldehydes. Exemplary use of the phosphoranes is shown in the C-7 chain functionalisation in synthetic estrones, which may be valuable precursors for radioligands in early breast cancer diagnosis.show more
