Complementary Reactivity of 1,6-Enynes with All-Metal Aromatic Trinuclear Complexes and Carboxylic Acids

The distinct reactivity of 1,6-enynes in the presence of a trinuclear metal complex activated by a carboxylic acid is presented. The triplatinum catalyst enables the cyclization of the substrate and subsequent incorporation of a nucleophile in the final product. In contrast, sequential cyclization/double bond shift occurs under analogous conditions in the presence of the corresponding tripalladium complex.

Hydroxy- and Alkoxycyclizations of Enynes Catalyzed by Platinum(II) Chloride

The cyclization of 1-en-6-ynes catalyzed by PtCl2 in the presence of water or alcohols affords five or six-membered ring carbocycles containing hydroxy or alkoxy functional groups in high yields. The alkoxycyclizations can also be performed wit

(Alkylthio)alkynes as addends in the Co(0) catalyzed intramolecular pauson-khand reaction. Substituent driven enhancements of annulation efficiency and stereoselectivity

Compared to terminal alkynes, (methylthio)alkynes are generally superior substrates for the thermally promoted, Co2(CO)8 catalyzed Pauson-Khand reaction of enynes and allenynes, providing enones in higher yields and with enhanced diastereoselectivity. Improvements in yield dependent upon the use of 2,2,2-trifluoroethanol as co-solvent and an apparent preference for endo selectivity with (ethoxy)alkynes are also disclosed.
