Aziridine Formation with Retention of Configuration from a Pentacoordinated 1,2-Thiazetidine Bearing Two Chiral Centers at the 3- and 4-Positions

Tetracoordinated and pentacoordinated 1,2-thiazetidines bearing the Martin ligand, trans-5 and trans-6, were synthesized as stable compounds. The X-ray crystallographic analyses showed that trans-5...
