4-benzyl-5-aminoisoquinolin-1-ones are close analogues of the water-soluble PARP-1 inhibitor 5-AIQ. Their synthesis was approached through Pd-catalysed cyclisations of N-(2-alkenyl)-2-iodo-3-nitrobenzamides. Reaction of N,N-diallyl-2-iodo-3-nitrobenzamide with Pd(PPh3)4 gave a mixture of 2-allyl-4-methyl-5-nitroisoquinolin-1-one and 2-allyl-4-methylene-5-nitro-3,4-dihydroisoquinolin-1-one.

Hypervalent Iodine-Mediated Alkene Functionalization: Oxazoline and Thiazoline Synthesis via Inter-/Intramolecular Aminohydroxylation and Thioamination
A metal‐free oxidative difunctionalization of N‐allylamides and N‐allylthioamides has been developed. This system features the use of a hypervalent iodine oxidant with electron‐deficient amines to access 5‐amino‐oxazoline and thiazoline scaffolds under mild conditions. Notably, various electron‐deficient amines were systematically evaluated and we verified the reaction profile was originated from an

addition, no added electrolytic salts are needed in this process. The developed method has been validated using two different hypervalent iodine-mediated transformations: (i) the oxidative cyclization of N-allylic and N-homoallylic amides to the corresponding dihydrooxazole and dihydro-1,3-oxazine derivatives, respectively, and (ii) the α-tosyloxylation of ketones. Both reactions proceeded smoothly under
