  Simple and condensed β-lactams. Part 14. Anomalous behaviour of 1-(4-methoxyphenyl)-4-(tetrazol-5-ylmethyl)azetidin-2-one towards cerium(IV) ammonium nitrate

  摘要：

  Treatment of 1-(4-methoxyphenyl)azetidin-2-one 7 with cerium(IV) ammonium nitrate (CAN) fails to yield the N-deprotected product 6. Depending on the mode of work-up, N-substituted products 8-13 are obtained instead. The formation of these products may be rationalized by assuming interaction of the nucleophilic tetrazole and electrophilic quinone imine moieties of intermediate 21 to afford, after deprotonation, the spirocyclic quinone aminal 25. The latter, in contrast to quinone imine derivatives of type 3, is stable to hydrolysis under the conditions applied but reacts readily both with added sodium chloride and bromide as well as with reducing agents (NaHSO3, I-).

  1-(4-Methoxypheny])azetidin-2-ones 5a–5g were acetoxylated by lead(IV) acetate to afford the corresponding compounds 6a, 6b, 6c' and 6d–6g. In the d series elimination products 9 and 10 were also formed. Ring homologue 7a afforded the hydrotylated derivative 8'a.

  用乙酸铅（IV）对1-（4-甲氧基苯基））氮杂环丁烷-2-酮5a-5g进行乙酰氧基化，得到相应的化合物6a，6b，6c '和6d-6g。在d系列中，还形成消除产物9和10。环同系物7a得到加氢衍生的衍生物8'a。
