Catalytic enantioselective cyclization and c3-fluorination of polyenes

(Xylyl-phanephos)Pt2+ in combination with XeF2 mediates the consecutive diastereoselective cation-olefin cyclization/ fluorination of polyene substrates. Isolated yields were typically in the 60-69% range while enantioselectivities reached as high as 87%. The data are consistent with a stereoretentive fluorination of a P2Pt-alkyl cation intermediate.

PdII- and PtII-mediated polycyclization reactions of 1,5- and 1,6-bienes: Evidence in support of carbocation intermediates

Pincer-ligated PdII and PtII dicationic complexes efficiently generate cations from 1,5- and 1,6-dienes. These transient cations can be selectively trapped with heteroatoms, alkenes, and through pinacol rearrangements. For example, trienyl-phenol 1 is converted into tetracyclic 2 in high yield and diastereomeric ratio (see scheme).
