  Total synthesis of dapiramicin B

  摘要：

  The first total synthesis of dapiramicin 13, a nucleoside antibiotic, is described. The characteristic N-glycoside linkage in dapirarnicin B was effectively constructed by way of the Pd-catalyzed coupling reaction of a heptopyranosylamine with a bromo-pyrrolopyrimidine derivative.
