摘要:The present invention discloses and claims five (5) novel, highly efficient synthetic routes for the total synthesis of enantiomerically-pure (i.e., 99%) 7-(2′-trimethylsilyl)ethyl camptothecin (BNP1350; Karenitecin; Cositecan). These aforementioned synthetic schemes are the first to disclose the total syntheses of 7-(2′-trimethylsilyl)ethyl camptothecin using a highly novel direct, non-linear and convergent synthetic strategy which involves annealing the key C7-(trimethylsilyl)ethyl side chain-bearing A ring key synthons to an enantiomerically-pure tricyclic pyridone; rather than through the conventional methodology which incorporates the C7-(trimethylsilyl)ethyl side chain as the final synthetic step on a totally synthesized camptothecin parent compound. The current novel synthetic approaches reported herein since utilize desirably functionalized A-ring with preinstalled trimethyl silyl ethyl side chain, the aforementioned synthetic methodologies have a wider scope of making wide range of pharmaceutically relevant A-ring substituted BNP1350 analogs by substituting desirably functionalized nitro or protected amino phenyl carboxy A-ring as the starting material.

标题 :Methods for synthesis of end-functionalized polyolefins

摘要:A strategy for the synthesis of semi-telechelic polyethylene through the palladium diimine-catalyzed chain transfer polymerization of ethylene using various silanes as chain transfer agents is reported. Polymer molecular weight and end-group chemical structure can be tuned by varying the chain transfer agent as well as its concentration. NMR spectroscopy confirms that the silicon of the chain transfer agent is incorporated into the polymer. The stability of the catalyst toward polar monomer enables the chain transfer polymerization of semi-telechelic poly(ethylene-methyl acrylate) copolymers.

标题 :Synthesis of hierarchical nanocrystalline zeolites with controlled particle size and mesoporosity

摘要:A one step synthesis of nanocrystalline zeolites ZSM-5 and Naβ from a single template system in high yield has been discovered. The size of individual nanocrystals, as well as mesopore surface area and pore volume can be controlled by adjusting the pH of the reaction mixture, as well as the hydrothermal treatment temperature and duration. The mesopore volume and size distribution show a dependence on particle size such that smaller particles lead to higher mesopore volumes and narrower pore size distributions.
