Simple and condensed β-lactams. Part 27. Reaction of 1-(4-methoxyphenyl)-4-(tetrazol-5-yl)azetidin-2-one and 1-(4-methoxyphenyl)-5-(tetrazol-5-yl-methyl)pyrrolidin-2-one with Cerium(IV) ammonium nitrate (CAN)

Treatment of pyrrolidinone 3a with CAN under the usual conditions leads to formation of spiro compound 12, rather than to N-demethoxyphenylation. A study of the reactions of compound 12 with sodium chloride and sodium iodide furnished the proof for our assumption that the related non-isolable compounds 6 and 11 are the intermediates of the anomalous reactions of compounds 1a and 2a, respectively, with CAN.
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

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 ra
