  Stereoselective synthesis of the bacterial DNA primase inhibitor Sch 642305 and its C-4 epimer

  摘要：

  A convergent stereoselective synthesis of the bacterial DNA primase inhibitor Sch 642305 and its non-natural epimer at C-4 is described. A key aspect was the construction of a trans-2,3-disubstituted cyclohexanone system by means of a stereoselective Michael addition/alpha-alkylation sequence. The macrolactone ring of either stereoisorner was created using the Mitsunobu and Yamaguchi procedures, respectively. (c) 2007 Elsevier Ltd. All rights reserved.

  Sch 642305 is a fungal nonanolide, which inhibits bacterial DNA primase and HIV-1 Tat transactivation. The enantioselective synthesis of Sch 642305 was succeeded starting from useful chiral building block via stereoselective dianion alkylation of beta-ketosulfoxide and lactonization.

  A highly convergent, enantioselective synthesis of (+)-Sch 642305 is presented, which features a Mukaiyama-Michael addition followed by allylation to establish the syn-anti relationship of the three contiguous stereocenters. The 10-membered macrolactone was formed through ring-closing metathesis.
