Spirotriazolines and spirooxadiazolines are furnished in high yields at room temperature by the light-induced [3+2] cycloaddition with 2,5-diaryltetrazole as the precursor of nitrile imine. The use of light as the unique reagent and broad substrate scope are distinguishing features of this protocol.

development of cancers. Thus detection of endogenous DNMT activities and efficient inhibition of DNMTs have important therapeutic significance. In this work, a small molecule activity-based probe (ABP) of DNA methyltransferase 1 (DNMT1), T1, was developed. The probe was a clickable analog of tryptophan and was able to covalentlylabel endogenous DNMT1 and inhibit its enzymatic activity more effectively than
