subsequently can be cleaved under very mild conditions by methanolysis. On the basis of this principle we developed a versatile and robust linker for solid-phase chemistry. The stability of the linker was demonstrated under acidic and basic conditions, and it was evaluated for its utility in peptide synthesis as well as for reductive amination, Pd-mediated C–C-coupling, and metathesis reactions.(© Wiley-VCH
双螺油酰胺实体的 Cu2+ 络合导致 N-C-酰胺键减弱,随后可以通过甲醇分解在非常温和的条件下裂解。在此原理的基础上,我们开发了一种用于固相化学的多功能且稳健的接头。在酸性和碱性条件下证明了接头的稳定性,并对其在肽合成以及还原胺化、Pd 介导的 C-C-偶联和复分解反应中的效用进行了评估。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
