The carbon-carbon bond-forming method in aqueous media was investigated by using indium as a single-electron transfer radical initiator. The indium-mediated intermolecular alkyl radical addition to imine derivatives and electron-deficient C=C bond proceeded effectively.

A new method for the synthesis of five- to eight-membered lactams by sulfanyl radical mediated-cyclisation of dienylamides is described.The sulfanyl radical addition-cyclisation of the dienylamide 1 was systematically investigated under four different conditions and was found to give the cyclised lactams 2-6 in 54-79percent yield.The stereo- and regio-selectivity of sulfanyl radical addition-cyclisation was established from the preferential formation of the trans-cyclised lactam 3 and also from the substituent effects in the cyclisation of the dienylamides 11-18.The sulfanyl radical mediated addition-cyclisation was successfully applied to the construction of the six- and eight-membered lactams 28a, b.
