Synthese und enzymatischer Abbau von Dendrimeren aus (R)‐3‐Hydroxybuttersäure und Trimesinsäure

Abstract: ZUSCHRIFTENweise, daB fur eine erfolgreiche Umsetzung sowohl das Alken als auch das Peroxid an Titanzentren koordiniert sein mussen. MPPH ist als Oxidationsmittel fur Cycloalkane inaktiv, was beweist, daB hier ein Radikalmechanismus vorliegt. Es ist nun vielfach belegt, daR es, wenn MPPH und TBHP in Gegenwart von Metallkatalysatoren zu unterschiedlichen Kohlenwasserstoff-Oxidationsprodukten fiihren, zwingende Griinde gibt anzunehmen, daI3 beide Hydroperoxide an einer Chemie freier Radikale und nicht an einer R… Show more

“…The discrete nature of the rosette assembly is quite intriguing from its applicability to the core of self-assembling dendrimers. [26] Since dendrimers act as hosts for guest encapsulation, [27] the stimuli-induced formation and deformation [28] of the dendritic architectures have significant meaning. Self-assembling dendrimers are capable of achieving such functions in an effective manner, that is, formation/dissociation of the dendrimers from/into the dendrons.…”

“…[34][35][36][37] For our current synthetic plans, we used Seebach's commercially available enantiopure (S)-Boc-BMI (1a, BMI = 2-tert-butyl-3-methylimidazolidin-4one). [33,38,39] This paper reports the results of our efforts to synthesize enantiopure γ-fluoro-α-amino acid derivatives and the corresponding α-methylated analogues by using enantiopure (S)-Boc-BMI (1a) as a chiral glycine building block. 2-Fluoroallyl tosylate, synthesized [40] in 90% yield from 2fluoroallyl alcohol [26] and tosyl chloride using NaOH/Et 2 O, was used as the alkylating agent.…”

“…Biologically active substances that are attached to the termini of dendritic structures [10] can be liberated by chemical or biological methods. [11] Several branched constructs have been reported which contain covalently linked doxorubicin molecules as end groups. [12][13][14] However, in all the branched structures or dendrimers reported so far, each single drug has to be independently cleaved to be released.…”
