权利人:THE TRUSTEES OF BOSTON COLLEGE
摘要:Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

标题:Abietanes and methods of making and using the same

摘要:In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein is versatile polyene cyclization strategy that exploits conjugated β-ionyl derivatives. Photomediated disruption of the extended Ï€-system within these chromophores unveils a contra-thermodynamic polyene that engages in a Heck-type cyclization to afford [4.4.1]-propellanes. The connectivity of overbred polycycles generated from this process is controlled by the position of the requisite C-Halide bond. Thus, compared to conventional biomimetic polyene cyclization, this approach allows for complete control of regiochemistry and facilitates incorporation of both electron-rich and electron-deficient (hetero)aryl groups. This strategy was successfully applied to the total synthesis of abietanes such as, for example, taxodione and salviasperanol, two isomeric abietane-type diterpenes that previously could not be prepared along the same synthetic pathway.

摘要:This invention provides a polymerization method, which yields nanostructured conjugate porous polymers. By applying in a successive manner ultrasound tip conditions and microfluidic techniques to water-organic solvent mixtures in presence of a surfactant, emulsions containing nanomicelles are formed. The polymerization occurs via metal-catalyzed cross-coupling reactions, condensation reactions or light-mediated free-radical reactions and leads to nanostructured conjugate porous polymers with reduced average particle size and narrow particle size dispersity. Such polymers are easy to process, thus, they can be used in a variety of applications, including the synthesis of hybrid organic-inorganic materials as well as in photocatalysis and in the production of thin films.
