What is a cyclic anhydride?
By definition, and etymologically speaking an anhydride function is obtained by dehydration of two acids. In other words, an anhydride function can be seen as the concomitant protection of a first acid and the activation of a second one. Cyclic anhydrides are no-end ring molecules and the majority are those derived from carboxylic diacids.
Does alternating copolymerization of aldehyde and cyclic anhydride make a recyclable polyester library?
Here, we develop a recyclable polyester library from the alternating copolymerization of aldehyde and cyclic anhydride. Although these two monomer sets have little or no thermodynamic driving force for homopolymerization, their copolymerization demonstrates the unexpected alternating characteristics.
Is cyclic anhydride copolymerized with cationic mechanism reversible?
The copolymerization of cyclic anhydride and OPA with the cationic mechanism exhibits alternating and reversible characteristics. The method is performed under mild conditions and produces polyesters in high yields within 1 h.
Can cyclic anhydride and epoxide be used to make polyester?
The alternating copolymerization of cyclic anhydride with epoxide is another chain-growth route to prepare polyesters (Fig. 1b) 42, 43, 44, 45, 46, 47. To date, more than 400 polyesters made of more than 20 cyclic anhydrides and 20 epoxides have been reported 48, 49, 50, 51, 52.
Are cyclic anhydrides pH-sensitive linkers?
This review intends to cover the last updates in the use of cyclic anhydrides as pH-sensitive linkers, their differences in reactivity and the latest applications found in bioconjugation chemistry, or chemical biology and when possible, in drug delivery. Key-words Cyclic anhydride, linker, pH-sensitive, charge reversal, smart delivery 2
Are cyclic anhydrides contaminated by hydrated diacids?
Due to energetic and stability reasons, commercially available cyclic anhydrides are usually 5- to 6-member dehydrated rings (Figure 1), yet some of them can be slightly contaminated by the corresponding hydrated diacid. 3 Figure 1: cyclic anhydrides predominantly used in bioconjugation, on which the present review focuses.
