Condensation of 5,6-dihydroindolo[2,1-a]isoquinoline with aromatic aldehydes in trifluoroacetic acid afforded 12-arylidene-5,6-dihydroindolo[2,1-a]isoquinolinium trifluoroacetates. Hydrogenolysis of these salts on rhenium heptasulfide at elevated temperature and hydrogen pressure yielded indolo[2,1-a]isoquinolines, while reduction with sodium borohydride gave 12-arylmethylindoloisoquinolines. Photoluminescence was found for some indolo[2,1-a]isoquinolines.

strategy, we broke this consensus and discovered a catalyst-free photodecarbonylation of the aldehyde group. It revealed that decarbonylation can be easily achieved with visible light irradiation by introducing a tertiary amine into the ortho-position of the aldehyde group. A diverse array of tertiary amines is tolerated by our photodecarbonylation under mild conditions. Furthermore, the (QM) computations

Under rhodium catalysis, N‐aziridinyl imines provided access to N‐fused indolines through non‐carbonyl‐stabilized rhodium carbenoid CHinsertion. The utility of this methodology for the synthesis of architecturally complex heterocycles was further demonstrated by an expedient total synthesis of (±)‐cryptaustoline (see scheme).

One-pot synthesis of 5,6-dihydroindolo[2,1-a]isoquinolines from gold-catalyzedannulations between N-(o-alkynylphenyl)imines and α-diazo esters is described. This cascade reaction involves an initial attack of the diazo ester at the imine to form cis-aziridine, followed by stereoselective [3 + 3]-annulations with the tethered arylalkyne. We have employed this new catalysis to prepare one bioactive
