Efficient Tandem Process for the Catalytic Deprotection of N-Allyl Amides and Lactams in Aqueous Media: A Novel Application of the Bis(allyl)–Ruthenium(IV) Catalysts [Ru(η3:η2:η3-C12H18)Cl2] and [{Ru(η3:η3-C10H16)(μ-Cl)Cl}2]

highly efficient methodology for the removal of the allyl protecting group in amides and lactams has been developed by using the commercially available bis(allyl)-ruthenium(IV) catalysts [Ru(eta(3):eta(2):eta(3)-C(12)H(18))Cl(2)] (C(12)H(18)=dodeca-2,6,10-triene-1,12-diyl) and [Ru(eta(3):eta(3)-C(10)H(16))(micro-Cl)Cl}(2)] (C(10)H(16)=2,7-dimethylocta-2,6-diene-1,8-diyl). The tandem process, which
通过使用市售的双(烯丙基)-钌(IV)催化剂[Ru(eta(3):eta(2): eta(3)-C(12)H(18))Cl(2)](C(12)H(18)= dodeca-2,6,10-triene-1,12-diyl)和[Ru( eta(3):eta(3)-C(10)H(16))(micro-Cl)Cl}(2)](C(10)H(16)= 2,7-二甲基辛基-2,6-二烯-1,8-二基)。串联过程发生在水性介质中并以一锅法进行,涉及烯丙基单元的C = C键的初始异构化和随后生成的烯酰胺的氧化裂解。
