and C-N bond fission. However, the hydrolysis of N-acyl beta-sultams is a sulfonyl transfer reaction that occurs with S-N fission and opening of the four-membered ring. Similar to other beta-sultams, the N-acyl derivatives are at least 10(6)-fold more reactive than N-acyl sulfonamides. 3-Oxo-beta-sultams are both beta-lactams and beta-sultams but also hydrolyze with preferential S-N bond fission.
[反应:见正文] N-酰基磺酰胺通常通过酰基转移和CN键裂变与亲核试剂反应。然而,N-酰基β-杜马酰胺的水解是随着SN裂变和四元环的打开而发生的磺酰基转移反应。与其他β-舒马酸相似,N-酰基衍生物的反应性比N-酰基磺酰胺至少高10(6)倍。3-Oxo-beta-sultams既是beta-内酰胺又是beta-sultams,但也具有优先的SN键裂变而水解。
