Macrocyclization via rhodium-catalyzed intramolecular [2 + 2 + 2] annulation of triynes has been explored in an aqueous-organic biphasic system. The biphasic system controls the concentration of hydrophobic substrates in the aqueous reaction phase and offers diluted reaction conditions without the use of a slow addition technique. The system also achieves selective cross-annulation between hydrophobic diynes and hydrophilic alkynes. Copyright

Here, we report an improved and short synthetic route to benzosultine-sulfone via [2+2+2] cyclotrimerization as a key step, starting with dipropargyl ether and 1,4-dibromo-2-butyne with an overall yield of 16%.
Ruthenium-catalyzed cyclotrimerization of α-amino-α-propargyl carboxylates and phosphonates with 1,6-diynes: Synthesis of α-CF3-containing phenylalanine derivatives and their P-analogs

Ruthenium-catalyzed cocyclotrimerization of α-amino-α-propargyl-α-trifluoromethyl carboxylates and phosphonates with functional 1,6-diynes gives the corresponding CF3-containing phenylalanine derivatives and their phosphorus analogs.
Ruthenium carbene mediated [2+2+2] cyclotrimerizations
Mallagaray, álvaro,Medina, Sandra,Domínguez, Gema,Pérez-Castells, Javier
supporting information; experimental part, p. 2114 - 2118 (2010/10/03)
Second-generation Grubbs catalyst and Hoveyda-Grubbs catalyst are able to catalyze both crossed [2+2+2] cyclotrimerization of diynes with alkynes and di- or trimerizations of diynes. Selection of the reaction conditions allows us to favor one particular p
