The first example of the Ru-catalyzed transfer oxygenative [2 + 2 + 1] cycloaddition of silyldiynes to produce bicyclic 2-silylfurans is described. This cyclization process was realized using nitrones as readily available and adjustable oxygen atom donors

2,3-Fused 4-phenylnaphthalen-1-yl carboxylates were synthesized in a step- and atom-economical manner using a ruthenium-catalyzed hydrocarboxylative cyclization of 1,7-diaryl-1,6-diynes and subsequent oxidative photocyclization. The scope of this novel two-step process was demonstrated by the construction of diverse structures from substrates with various tethers and terminal aryl groups. Late-stage C-H functionalizations of the arylnaphthalene product further enhance the synthetic potential of the developed process. Light a fuse! 2,3-Fused 4-phenylnaphthalen-1-yl carboxylates were synthesized in a step- and atom-economical manner using a ruthenium-catalyzed hydrocarboxylative cyclization of 1,7-diaryl-1,6-diynes and subsequent oxidative photocyclization. Late-stage C-H functionalizations of the obtained arylnaphthol derivatives further enhance the synthetic potential of the developed process (see scheme).
Ruthenium-catalyzed transfer oxygenative cyclization of α,ω-diynes: Unprecedented [2 + 2 + 1] route to bicyclic furans via ruthenacyclopentatriene

A novel oxygen-atom-transfer process enables the catalytic [2 + 2 + 1] synthesis of bicyclic furans from α,ω-diynes with DMSO. [CpRu(AN)3]PF6 catalyzed the transfer oxygenative cyclization of diynes with aryl terminal groups, while t
