  Practical asymmetric synthesis of a novel γ-secretase inhibitor

  摘要：

  An efficient route to gamma-secretase inhibitor hydroxyl thiophene sulfonamide 1 is described. The approach contains nine steps with an overall yield of 8%. The synthesis highlights a diastereoselective methylation using Evans' oxazolidinone method and a chiral Strecker reaction via Davis' sulfonimine protocol. (c) 2008 Elsevier Ltd.
