  Development of a One-Pot Four C–C Bond-Forming Sequence Based on Palladium/Ruthenium Tandem Catalysis

  摘要：

  A one-pot four C-C bond-forming sequence has been developed using two distinct transition metal complexes. The sequence entails a double Pd-catalyzed allylic alkylation followed by a Ru-catalyzed ring-closing metathesis and a Pd-catalyzed Heck coupling. The use of various active methylene nucleophiles was examined with yields up to 76% (93% per C-C bond).

  cyclopentenes and 4,5-dihydrofurans with different substitution patterns were performed starting from the same materials (i.e., 2-(2',3'-allenyl)acetylacetates). Depending on the choice of metal catalyst, the Au-catalyzed reaction afforded C-attack-5-endo cyclization products 2, whereas the Pd-catalyzed one led to the formation of O-attack-5-exo cyclization products 3. The selectivity may be explained by the

  从相同的材料（即2-（2'，3'-烯基）乙酰乙酸酯）开始，高效地合成具有不同取代方式的环戊烯和4,5-二氢呋喃。根据金属催化剂的选择，Au催化的反应提供了C-attack-5-exo环化产物2，而Pd催化的反应导致了O-attack-5-exo环化产物3的形成。可以通过底物和催化剂的空间和电子效应来解释。

  An allylic alkylation/ring-closing metathesis domino catalytic process, wherein a palladium and a ruthenium catalyst are concomitantly present in the reaction mixture from the outset of the reaction, is developed. Evidence for Grubbs' catalysts activity in allylic alkylation is also reported.
