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
