WebAlkoxycarbonyl groups can be readily installed on carbohydrates by reaction with the corresponding chloroformates in the presence of TMEDA at low temperature. The mild reaction conditions can be modulated to attain regioselective protections. WebA simple and an efficient approach has been developed for the synthesis of polyesters containing pendant thiolactone units. For this purpose, polyester P1 possessing electron deficient triple bonds in the main backbone was prepared, and subsequently reacted with benzyl-azide and thiolactone-azide (TLa-N 3) at a mole ratio of 2:1 (per alkyne), through …

WebFor olefins, cyclic, or better hi- or tricyclic ring structures with large ring strain (norborn-2-enes or norbornadienes for instance) are required. Alternatively, 1-alkynes can be used. In this case, the term 1-alkyne polymerization applies. This reaction proceeds via a- or j6-insertion of the alkyne into the metal-carbon double bond (Scheme 1).
