Phosphonium-supported tin reagents and catalysts were prepared and were shown to be effective in Stille couplings, radical dehalogenations, radical cyclizations, and carbonyl allylations. Not only could the tin residues be removed from the crude reac

Studies dealing with the diastereoselective installation of nine stereogenic centers of the C-12-C-25 subunit of bafilomycin A 1 1 are described. A spiroketal precursor has been chosen as a rigid scaffold owing to the central spiro center, the config

International audience; Current efforts devoted to the synthesis of Bafilomycin A1 led us to investigate a synthetic route through a spiroketal intermediate for the construction of the C15-C25 subunit. Preliminary studies for the diastereoselective i
