  An efficient and versatile synthesis of acylpolyamine spider toxins

  摘要：

  An efficient and versatile synthesis of acylpolyamine spider toxins was developed based on the structural classification of the Nephila and Nephilengys spider toxins using the 2-nitrobenzenesulfonamide protecting group. The naturally occurring toxins 1-5 representing each structural type have been efficiently synthesized by this method in a high overall yield with few steps. (C) 2002 Elsevier Science Ltd.

  An efficient and versatile synthesis of acylpolyamine spider toxins of all structural types classified by extensive MS analysis has been achieved. By using 2-nitrobenzenesulfonamide as an effective activating and/or protecting group (the Nosyl strategy), the naturally occurring toxins 1-8 corresponding to Types A-F were concisely synthesized in high overall yield.
