  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.

• An Efficient and Highly Diastereoselective Synthesis of GSK1265744, a Potent HIV Integrase Inhibitor
  作者：Huan Wang、Matthew D. Kowalski、Ami S. Lakdawala、Frederick G. Vogt、Lianming Wu

  DOI：10.1021/ol503580t

  日期：2015.2.6

  A novel synthesis of GSK1265744, a potent HIV integrase inhibitor, is described. The synthesis is highlighted by an efficient construction of the densely functionalized pyridinone core as well as a highly diastereoselective formation of the acyl oxazolidine moiety. The latter exploits the target molecule’s ability to chelate to Mg2+, a key feature in the integrase inhibitor’s mechanism of action.

  An efficient method for the preparation of β-amino-α,β-unsaturated carbonyl compounds is demonstrated. Bench-stable sodium 3-oxo-enolates were prepared from carbonyl compounds, and reacted with amines in the presence of an acid and a desiccant. DFT studies revealed contrasting mechanisms toward the reactivity of aliphatic amines in protic solvents and aromatic amines in aprotic solvents. While the
