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 tetrahydrooxa-zin-2-one ring (7, 8a-k) via neighboring group participation. Under similar conditions, 16β-aminomethyl-3-methoxy-17β-tosylestra-1,3,5(10)-triene (4) decomposes into 16-methylene-3-methoxyestra-l
在DMSO / NaHCO 3系统中,16α-氨基甲基-,16α-苄基氨基甲基-和取代的苄基氨基-3-甲氧基-17β-甲苯磺酰氧基-1,3,5(10)-三烯(3,5a-k)不会发生氧化,但通过相邻基团的参与形成四氢氧杂嗪2酮环(7,8a-k)。在类似条件下,16β-氨基甲基-3-甲氧基-17β-甲苯磺酰基-1,3,5(10)-三烯(4)分解成16-亚甲基-3-甲氧基乙-1,3,5(10)-trien- 17一(12)。
