Abstract

Photochemical cyclization of N-allyl-N-(2-formylphenyl)-4-methylbenzenesulfonamide in DMSO under irradiation with a light-emitting diode at λ 365 nm afforded 29% of 3-(4-methylbenzenesulfonyl)-1,1a,2,3-tetrahydro-7bH-cyclopropa[c]quinolin-7b-ol. The reaction is diastereoselective, and it requires no catalysis.
