ring-opening strategy to transform acyl, sulfonyl or carbamate protected aminocyclopropanes into 1,3-dielectrophilic carbon intermediates bearing a halide atom (Br, I) and a N,O-acetal. Replacing the alkoxy group of the N,O-acetal can be achieved under acidic conditions through an elimination-addition pathway, while substitution of the halides by nucleophiles can be done under basic conditions through a SN 2 pathway

cleavage/alkynylation of cycloalkylamides for the aminoalkyne synthesis undermildphotoredoxcatalysisconditions. γ- and δ-Aminoalkynes with versatile alkyne and amine substituents are efficiently constructed from cyclopropylamides and cyclobutylamides via amidyl radicals enabled by hypervalentiodine(III) reagents. The catalytic amount of cyclic iodine(III) BI’-OAc facilitated the single-electron oxidation and ring-opening
