  Stereoselective synthesis of 4-piperidone and 4-aminotetrahydropyridine derivatives by the imino Diels-Alder reaction of 2-amino-1,3-butadienes

  摘要：

  2-Amino-4-(alkoxymethyl)-1,3-butadienes react smoothly with nonactivated aldimines derived from aromatic aldehydes in the presence of ZnCl2 as Lewis acid giving rise, with good yields and very high stereoselectivity, to substituted 4-aminotetrahydropyridines which upon hydrolysis yield 4-piperidone derivatives. Moreover, the stereochemistry of the cyclization process depends on the nature of the N-substituent of the imine.

  Catalytic aminomercuration reactions of 3-alken-1-ynes: an improved method for the synthesis of 2-amino-1,3-butadienes and 1-aza-1,3-butadienes

  摘要：

  Catalytic aminomercuration of 3-alken-1-ynes leads to 1-aza-1,3-butadienes and 2-amino-1,3-butadienes. Under appropriate reaction conditions it is possible to prepare these compounds via mercuration of 3-alken-1-ynes in the presence of either aromatic or aliphatic primary and secondary amines. Depending on the substituents in the starting 3-alken-1-yne, the mercuration reaction may afford gamma-amino enamines instead of 2-amino-1,3-butadienes and 3-imino amines or 4-amino-1-aza-1,3-butadienes instead of 1-aza-1,3-butadienes.

• Stereoselective Synthesis of Seven-Membered Carbocycles from 2-Amino-1,3-butadienes and Vinyl Chromium Fischer-Type Carbenes

  Seven-membered ring carbocycles are prepared by reaction of easily avaliable 2-amino-1,3-butadienes with vinyl Fischer carbenes. Hydrolysis of the cycloadduct initially formed gives rise to cyclohepta-1,3-diones with total regio- and stereoselectivity in a one-pot process. When 2-aminobutadienes bearing a prolinol derivative as a chiral auxiliary are used, the corresponding cyclic diketones are obtained with very high enantiomeric excesses. The absolute configuration of the stereogenic centers generated was determined with the aid of ROESY and CD measurements.
