NEW SYNTHESIS OF STEROIDAL TETRAHYDROOXAZIN-2-ONES

In the DMSO/NaHCO3 system, 16α-aminomethyl-, 16α-benzylaminomethyl- and substituted benzylaminomethyl-3-methoxy-17β-tosyloxyestra-1,3,5(10)-triene (3, 5a-k) do not undergo oxidation, but form a tetrahydrooxazin-2-one ring (7, 8a-k) via neighboring group p
