New applications of the protecting group di-(4-methoxyphenyl)methyl: N-protection of urethanes and uridines, and efficient removal by either ceric ammonium nitrate/silica or 2,3-dichloro-5,6-dicyanoquinone

The protecting group di-(4-methoxyphenyl)methyl, removable by ceric ammonium nitrate on silica or 2,3-dichloro-5,6-dicyanoquinone, is shown to facilitate syntheses of urethanes (eg vinyl urethane, 1a) and uridine derivatives (eg 2-O-allyluridine, 8).
