A direct alkoxycarbonylation/cyclization reaction is accomplished under visible light-induced photoredox catalysis. With this approach, a variety of ester-substituted indolo[2,1-a]isoquinolines are prepared in good to excellent yields. It is worth noting that this method not only can afford the synthesis of indolo[2,1-a]isoquinolines but also can provide an alternative route for generating complex target structures bearing carboxylic esters.

Three chiral bisthionooxalamides were synthesized by acylation with ethyl or (1R)-menthyl chloroxoacetate of the corresponding diamines and subsequent thionation with Lawesson's reagent. Single crystal X-ray diffraction analysis revealed that products 4b-

(Diacyloxyiodo)arene was treated with electron-deficient olefins in the presence of hydrogen donor such as 1,4-cyclohexadiene to give the reductive addition products via alkyl radical through the radical decarboxylative pathway in good yields.Moreover, this system was able to generate either alkoxycarbonyl radicals or alkyl radicals with benzene, which was prepared from alcohol, oxalyl chloride, and (diacetoxyiodo)benzene via two steps, depending on reaction conditions.These radicals were also utilized for C-C bond formation with electron-deficient olefins.
