Copper-Mediated Synthesis of N-Acyl Vinylogous Carbamic Acids and Derivatives: Synthesis of the Antibiotic CJ-15,801
摘要:
Copper(I)-mediated C-N bond formation has been employed to prepare both N-acyl vinylogous carbamic acids and ureas. The novel N-acyl vinylogous carbamic acid antibiotic, CJ-15,801, was synthesized using this methodology.

A flexible route to the proposed structure of FR252921, a novel immunosuppressive agent, is developed. The key elements include the assembly of its two P-hydroxy acid residues via asymmetric aldol condensation of N-acylthiazolidinethinones with aldehydes, and its triene part via a CuI/N,N-dimethylglycine catalyzed Sonogashira coupling and subsequent isomerization. Using this strategy (13R,14R,19R)-FR252921 is elaborated. (c) 2006 Elsevier Ltd. All rights reserved.
Copper-Catalyzed Vinylation of Hydrazides. A Regioselective Entry to Highly Substituted Pyrroles

DOI:10.1021/ol062978s
日期:2007.3.1
A modular route to highly substituted pyrroles has been developed. This transformation consists of two sequential copper-catalyzed vinylations of bis-Boc-hydrazine followed by thermal rearrangement/cyclization. A wide variety of functionalized pyrroles can be prepared in a selective manner from simple and easily accessible precursors.
CuI/<i>N</i>,<i>N</i>-Dimethylglycine-Catalyzed Coupling of Vinyl Halides with Amides or Carbamates

日期:2004.5.1
The Cul-catalyzed coupling reaction of vinyl halides with amides or carbamates proceeds well at room temperature to 80 degreesC in dioxane to give enamides using NN-dimethylglycine as the promoter and Cs2CO3 as the base. The geometry of the C-C double bond is retained during the reaction course.
