  Microwave-Assisted Tandem Cross Metathesis Intramolecular Aza-Michael Reaction:  An Easy Entry to Cyclic β-Amino Carbonyl Derivatives

  摘要：

  Hoveyda-Grubbs catalyst in combination with BF3 center dot OEt2 efficiently promotes tandem cross metathesis intramolecular aza-Michael reaction between enones and unsaturated carbamates resulting in the creation of beta-amino carbonyl units. The use of microwave irradiation dramatically accelerates the process, enhancing the synthetic utility of this methodology for the preparation of these types of derivatives. When enantiomerically enriched alpha-branched amines were used as starting materials, the process was also very efficient, although with modest selectivity in the newly created stereocenter. The use of microwave irradiation led to an interesting effect, inverting the selectivity in the addition process.

  The oxidation of primary alcohols and aldehydes to the corresponding carboxylic acids is a fundamental reaction in organic synthesis. In this paper, we report a new chemoselective process for the oxidation of primary alcohols and aldehydes. This metal-free reaction features a new oxidant, an easy to handle procedure, high isolated yields, and good to excellent functional group tolerance even in the

  N‐Sulfinyl amines have been successfully employed as nitrogen nucleophiles for the asymmetric intramolecular aza‐Michael reaction. The synthetic strategy involves a cross‐metathesis reaction followed by the Michael‐type cyclization, either in a base‐catalyzed two‐step procedure or in a tandem fashion. The developed methodology allows access to chiral substituted pyrrolidines and piperidines bearing
