  Catalytic Antibodies in Synthesis:  Design and Synthesis of a Hapten for Application to the Preparation of a Scalemic Pyrrolidine Ring Synthon for Ptilomycalin A

  摘要：

  A catalytic antibody-based approach toward the synthesis of an optically active pyrrolidine ring synthon potentially useful for ptilomycalin A is described. Enantiomerically pure hapten 37 was designed and constructed with the eventual goal of generating antibodies for the enantioselective partial hydrolysis of a meso diester such as 44 into a monoacid 45. This transition state analog possesses a phosphonate group containing the requisite oxyanionic character of the tetrahedral intermediate for ester hydrolysis. A newly developed carbamate-based linker, which was found to be much more hydrolytically stable than the commonly used glutarate ester, was developed for coupling of the hapten to a carrier protein.

  日期：2018.8.3

  This work illustrates a reductive cross-electrophile coupling protocol for trifluoromethylation of alkyl iodides under Cu-catalyzed/Ni-promoted reaction conditions. The use of diboron esters as the terminal reductant allows the effective generation of the alkyl–CF3 products with excellent functional group tolerance and broad substrate scope. A mechanism involving a reaction of alkyl–Cu with Togni’s

  日期：2013.1

  Abstract A simple protocol for the preparation of N-protected amino alkyl thiols is reported that employs a reaction of sodium trithiocarbonate (Na2CS3) with N-protected amino alkyl iodides. Na2CS3 is easy to prepare and the protocol circumvents the use of strong bases and multiple steps. All the thiol compounds made were obtained as enantiopure samples and were characterized employing NMR and mass

• Novel cyclic β-aminophosphonate derivatives as efficient organocatalysts for the asymmetric Michael addition reactions of ketones to nitrostyrenes
  作者：Triana Widianti、Yoshikazu Hiraga、Satoshi Kojima、Manabu Abe

  DOI：10.1016/j.tetasy.2010.05.049

  日期：2010.8

  Three novel catalysts based upon cyclic beta-aminophosphonate derivatives 1-3 were designed to catalyze the asymmetric Michael addition reactions of ketones to p-nitrostyrenes. Among the catalysts that have been prepared in this study, cyclic beta-aminophosphonic acid monoethylester 3 showed the highest catalytic ability, giving the corresponding Michael adduct in good yields, high enantioselectivities (up to 92% ee), and high diastereoselectivities (syn:anti up to 95:5).
