Multiply substituted cyclobutanols are pivotal synthetic intermediates for constructing complex molecular architectures via ring-opening strategies. The development of efficient methods these valuable building blocks has garnered significant interest in the chemical community. In this work, we have described a novel silver(I)-catalyzed tandem cyclization–cycloaddition–isomerization sequence with bicyclobutanes and 2-alkynylbenzaldoximes, which offered an effective route to multiply cyclobutanols. This protocol features mild conditions, remarkable stereospecificity, broad substrate scope, excellent functional group tolerance. addition, application potential reaction was readily proven by its high efficiency reactants bearing biological moieties scale-up experiments.

Here, we report a protocol for the synthesis of skipped dienes through cross-coupling bicyclo[1.1.0]butanes with trifluoromethyl triftosylhydrazones. The reaction is run using TpBr3Cu(NCMe) as catalyst to give access library trifluoromethylated (32 examples, ≤98% yield) excellent E/Z selectivity under mild and operationally safe conditions. presented methods proved be compatible various functionalized
