[3 + 2]-Cycloadditions of nitrile ylides after photoactivion of vinyl azides under flow conditions

The photodenitrogenation of vinyl azides to 2H-azirines by using a photoflow reactor is reported and compared with thermal formation of 2H-azirines. Photochemically, the ring of the 2H-azirines was opened to yield the nitrile ylides, which underwent a [3 + 2]-cycloaddition with 1,3-dipolarophiles. When diisopropyl azodicarboxylate serves as the dipolarophile, 1,3,4-triazoles become directly accessible starting from the corresponding vinyl azide.
Synthesis of isoquinolines from α-aryl vinyl azides and internal alkynes by Rh-Cu bimetallic cooperation

Catalysts in a relay: A synthetic method for delivering highly substituted isoquinolines has been developed (see scheme; Cp =C5Me5, DMF=N,N-dimethylformamide, TEMPO=2,2,6,6-tetramethylpiperidine-1-oxyl). A preliminary mechanistic study showed that the rhodium and copper cooperate synergistically in the multistep sequence.
