标 题 :Synthesis of l-azatyrosine using pseudoephedrine as a chiral auxiliary
发明人：MYERS ANDREW G
权利人:CALIFORNIA INST OF TECHN
摘要:A practical synthesis of the potential chemotherapeutic agent L-azatyrosine is described. The key step involved the alkylation of (R,R)-(-)-pseudoephedrine glycinamide with 5-benzenesulfonyloxy-2-iodomethylpyridine and proceeded in 70-95% yield and 89-95% de. Simultaneous hydrolysis of the auxiliary and the benzenesulfonate protecting group afforded L-azatyrosine of ≧99% ee in 73% yield on multigram scale (recovery yield of (R,R)-(-)-pseudoephedrine: 90%).

标 题 :Radical cascade-enabled synthesis of precision polymers with complex main-chain structures
发明人：NIU JIA; HUANG HANCHU; WANG WENQI
权利人:TRUSTEES 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.
