  A sequential reaction process to assemble polysubstituted indolizidines, quinolizidines and quinolizidine analogues

  摘要：

  The omega-iodo-alpha,beta-alkynoates and their ketone, sulfone or phosphonate analogues react with delta-chloropropylamines in MeCN assisted with K2CO3 to undergo a sequential S(N)2/Michael addition/S(N)2/S(N)2 reaction process, giving polysubstituted indolizidines or quinolizidines in good to excellent yields. This sequential reaction process is also compatible with three other substituted alpha,beta-alkynoates, affording quinolizidine analogues in moderate to good yields. (c) 2006 Elsevier Ltd.
