  Enantioselective Synthesis of Antiinfluenza Compound A-315675

  摘要：

  Drug discovery efforts at Abbott Laboratories have led to the identification of influenza neuraminidase inhibitor A-315675 (1) as a candidate for development as an antiinfluenza drug. A convergent, stereoselective synthesis of this highly functionalized pyrrolidine is reported that utilizes pyrrolinone 2 as the key intermediate. The C5, C6 stereochemistry was established through a diastereoselective condensation of chiral imine compound 3 with silyloxypyrrole 4 to give pyrrolinone 2. The stereochemical outcome of this reaction depended critically on the choice of the imine functional group (FG), with tritylsulfenyl and (R)-toluenesulfinyl providing the desired products in good yields as crystalline intermediates. Conversion of pyrrolinone 2 into 1 was accomplished in seven subsequent steps, including Michael addition of cis-1-propenylcuprate at C4 and introduction of a cyano group as a carboxylic acid equivalent at C2.

  A concise, stereocontrolled, and practical synthesis of a neuraminidase inhibitor consisting of a highly functionalized D-proline scaffold is described. Key features involve a stereocontrolled addition of a propiolate ester to a chiral nonracemic nitrone derived originally from D-serine and the manipulation of acyclic and cyclic motifs en route to the target in 12.8% overall yield over 22 steps.

  A practical synthesis of neuraminidase influenza inhibitor, A-322278, has been developed. Asymmetry is introduced into the synthesis by an enzyme mediated ester hydrolysis. A highly diastereoselective vinylogous Mannich condensation reaction of N-Boc-2-tert-butyldimethylsilyloxypyrrole (TBSOP) and an N-(triphenylmethylsulfenyl)imine proceeds under thermodynamic control to assemble the framework.

  The chiral and stereoselective total synthesis of A-315675 1, an antiinfluenza agent, is described. The vicinal diamino moiety in 1 was stereoselectively constructed by the cascade Overman rearrangement of a vicinal allylic-homoallylic diol derived from D-tartrate. (c) 2007 Elsevier Ltd.
