  Construction of Hydroxylated Alkaloids (.+-.)-Mannonolactam, (.+-.)-Deoxymannojirimycin, and (.+-.)-Prosopinine through Aza-Annulation

  摘要：

  The aza-annulation of beta enamino carbonyl substrates with acrylate derivatives provides an efficient and convenient route for the regioselective construction of delta-lactams. This two-step ring-forming sequence involved initial generation of the benzyl enamine through either a condensation or conjugate addition reaction with BnNH(2), followed by aza-annulation with acryloyl chloride or acrylic anhydride. Controlled by the rigid framework of the intermediate lactam, introduction of ring substituents was accomplished with high relative stereoselectivity. The carbonyl functionality, which was necessary to direct the regioselectivity of the aza-annulation reaction, was then transformed into a protected hydroxyl substituent through Baeyer-Villiger oxidation. The resultant delta-lactam product was used as a valuable intermediate in the synthesis of three natural products. Subsequent modification of this delta-lactam gave the naturally occurring alpha-mannosidase inhibitors (+/-)-mannonolactam and (+/-)deoxymannojirimycin, while synthesis of the alkaloid (+/-)-prosopinine was accomplished through homologation of the lactam carbonyl.

  The synthesis of a series of pyridones, from their 2-hydroxypyridine or 2-methoxypyridine precursors, is described, along with studies into their reductions to saturated heterocycles. A number of 5-acylpyridones were prepared and were evaluated as substrates for asymmetric transfer hydrogenation prior to conversion to saturated heterocycles. The enantioselective reduction of 5-acetyl-1-benzylpyrimidine-2,4(1H,3H)-dione is also described. (C) 2014 Elsevier Ltd. All rights reserved.
