Synthesis of novel (3a,S)-1-aryl/aryloxy/alkoxy-3a,4-dihydro-3H-1λ5- [1,3,2]oxazaphospholo [3,4-a] indole-1-ones, thiones, and selenones was achieved in two steps with high yields from 2,3-dihydro-1H-indol-2(S)yl methanol (1) and dichlorophenyl phosphine/ethyl dichlorophosphite (2a and b) in the presence of triethylamine in dry THF followed by treatment with hydrogen peroxide, sulfur, and selenium. The compounds 4g-k have been synthesized by the direct cyclocondensation of 1 with different substituted phenyl phosphorodichloridates (2c-e, g) and bis(2-chloroethyl) phosphoramidic dichloride (2f).
