  abstract  = {Die tert.-Butyloxycarbonyl-Gruppe (Boc) l{\"a}ßt sich mittels reiner Trifluoressigs{\"a}ure nicht selektiv neben dem Benzyloxycarbonyl-Rest (Z) abspalten. Das gelingt auch nicht mit L{\"o}sungen von Trifluoressigs{\"a}ure bzw. Chlorwasserstoff in organischen L{\"o}sungsmitteln. Kern-substituierte Z-Gruppen wie Z(pCl), Z(mCl) oder Z(pNO₂) sind zwar stabiler, werden aber von den obengenannten Reagenzien ebenfalls angegriffen bzw. sind nicht mehr acidolytisch abspaltbar. - Mit 70proz. w{\"a}ßriger Trifluoressigs{\"a}ure gelingt die Abspaltung von Boc neben Z dagegen fast selektiv; dabei werden aber Benzylester, besonders Glutamins{\"a}ure-γ-benzylester, teilweise hydrolysiert, w{\"a}hrend Methyl- sowie {\"A}thylester nahezu best{\"a}ndig sind. Die Brauchbarkeit des Abspaltungsverfahrens wird anhand der schrittweise durchgef{\"u}hrten Synthese zweier Heptapeptid-Derivate gezeigt. - {\"A}hnlich spezifisch gelingt die Abspaltung von Boc mit Bortrifluorid-{\"a}therat in Eisessig; Benzylester sind gegen{\"u}ber diesem Reagenz stabiler als gegen w{\"a}ßrige Trifluoressigs{\"a}ure. Das Bortrifluorid-Verfahren eignet sich besonders f{\"u}r die Abspaltung von Boc-Gruppen neben s{\"a}urelabilen Thiol-Schutzgruppen (Tetrahydropyranyl- bzw. Trityl-Rest) sowie neben dem Cyclocystinyl-Rest. Die Leistungsf{\"a}higkeit der Methode wird durch die Synthese zweier Peptid-Derivate mit S-Trityl-Schutzgruppen belegt. Als Nebenreaktion ist die Acetylierung von aliphatischen Hydroxylgruppen m{\"o}glich. Sie l{\"a}ßt sich vermeiden, wenn man die Spaltung in anderen L{\"o}sungsmitteln durchf{\"u}hrt. Die als Modellverbindungen f{\"u}r Stabilit{\"a}tsuntersuchungen verwendeten Nε-acylierten Lysin-Derivate werden mit dem Aminos{\"a}ureanalysator quantitativ neben Lysin bestimmt.},
