Diversifying Polyhydroxyalkanoates – End-Group and Side-Chain Functionality
Background: Polyhydroxyalkanoates (PHAs) are a natural origin biodegradable polyesters consisted of various 3- and 4-hydroxyacid derived repeating units produced by microorganisms as energy storage. PHAs have been intensively studied due to their biodegradability and biocompatibility enabling their use both in packaging and agriculture as well as in medicine and pharmacy. PHAs obtained via biotechnol Read More

Polymers Tailored for Controlled (Bio)degradation Through End-Group and In-Chain Functionalization
Authors: Joanna Rydz, Marta Musiol and Marek KowalczukBackground: Currently, polymers can be created with specific properties that are tailored to a wide range of applications from medical to everyday products as packaging. There are different techniques to prepare novel polymer materials with various architectures and specific groups via a variety of reaction mechanisms of different complexity. End-group modification of polymers is a powerful tool for tailoring polymer prop Read More

Biodegradable Polyurethanes Cross-Linked by Multifunctional Compounds
More LessBackground: Cross-linking structure of polyurethanes determines no degradability of these materials. However, introducing the hydrolysable substrates (of natural or synthetic origin) into the cross-linked polyurethanes structure makes them biodegradable. Moreover compounds (such as polycaprolactone triol, glycerin, lysine triisocyanate, etc.) that are used for polyurethane cross-linking are degraded in non-toxic product Read More

Functionalized Chitosan for Pharmaceutical Applications
Authors: Catalina Natalia Cheaburu-Yilmaz, Sinem Yaprak Karavana and Onur YilmazBackground: Chitosan structure versatility toward a change in an external stimulus represents a “must have” for the pharmaceutical applications, especially for the pharmaceutical formulations. Chemical modification can open new ways to obtain materials with tailored properties. Despite the great interest for conventional graft modifications, controlled/living free radical polymerizations (i.e. RAFT, ATRP, etc.) and advanced che Read More

Synthesis of Phosphonates via Michaelis-Arbuzov Reaction
Background: Michaelis–Arbuzov reaction has played a key role for the synthesis of dialkyl or diaryl phosphonates by reacting various alkyl or aryl halides with trialkyl or triaryl phosphite. This reaction is very versatile in the formation of P-C bond from the reaction of aliphatic halides with phosphinites or phosphites to yield phosphonates, phosphinates, phosphine oxides. The Arbuzov reaction developed some methodologie Read More

Synthesis of N- and O-Containing Macrobicycles with Central Biphenyl Moiety via Pd(0)-Catalyzed Amination Reactions
Background: Simple, efficient and enough versatile approaches to macrobicycles and macrotricycles, which are of great interest for the coordination of metal cations, were proposed in early 1990s using nucleophilic substitution reactions. Our research group was the first to begin a wide-range synthesis of N- and Ocontaining macrocycles using Pd-catalyzed amination reactions. Objective: The goal of the present res Read More
