摘要:Abstractmagnified Imagethe Visible‐light‐induced Transformation Of Toluenes With N‐bromosuccinimide (Nbs) Under Solvent‐free Reaction Conditions (Sfrc) Was Studied. The Reaction Took Place In Spite Of The Very Restricted Molecular Motion; Toluenes Could Be Regioselectively Converted To Benzyl Bromides. Selective Radical‐chain Reactions With Nbs Were Carried Out In Liquid/liquid And In Solid/solid Systems; Furthermore,Reactions Could Be Performed In The Presence Of Air. The Radical Scavenger Tempo (=2,2,6,6‐tetramethylpiperidin‐1‐yloxy) Completely Suppressed The Side‐chain Bromination Of Toluenes With Nbs Under Sfrc. Electron‐withdrawing Groups Decreased The Reactivity Of The Toluenes,And The Hammett Reaction Constant ρ+=−1.7 Indicated Involvement Of Polar Radical Intermediates With Electrophilic Character.

标题 :Synthesis of cyclic carbonate monomers
发明人：PARK NATHANIEL H; HEDRICK JAMES L; PIUNOVA VICTORIA A; ARRECHEA PEDRO; ERDMANN TIM
权利人:IBM
摘要:Techniques regarding the synthesis of cyclic carbonate monomers are provided. For example, one or more embodiments described herein can comprise a method, which can include cyclizing a functionalized diol monomer with N,N′-carbonyldiimidazole, wherein the cyclizing produces a cyclic carbonate monomer and an imidazole carbamate. The method can also include activating the imidazole carbamate with an acid, wherein the activating promotes cyclization of the imidazole carbamate into the cyclic carbonate monomer.

权利人:SCRIBAN CORINA; GLUECK DAVID S; DARTMOUTH COLLEGE
摘要:The present invention relates to a process for preparing an enantioenriched phosphorus-stereogenic, tertiary phosphine. Secondary phosphines are contacted with an alkyl halide and base in the presence of a chiral metal catalyst thereby producing the enantioenriched phosphorus-stereogenic, tertiary phosphine for subsequent use in homogeneous catalysis reactions.

发明人：JONES J BRYAN
权利人:UNIV TORONTO
摘要:The present invention relates to modified enzymes with one or more amino acid residues from an enzyme being replaced by cysteine residues, where at least some of the cysteine residues are modified by replacing thiol hydrogen in the cysteine residue with a thiol side chain to form a modified enzyme, wherein the modified enzyme has high esterase and low amidase activity. Also, a method of producing the modified enzymes is provided. The present invention also relates to a method for using the modified enzymes in peptide synthesis.
