Published: November 2010

AI Article Synopsis

  • - The natural product essramycin was synthesized using a two-step reaction without protective groups and involved a 3-amino-1,2,4-triazole intermediate.
  • - The synthetic version of essramycin had its structure clearly identified.
  • - Unlike the natural product, the synthetic essramycin showed no antibacterial activity.

Article Abstract

The triazolopyrimidine natural product essramycin (1) was synthesized without the use of protecting groups via a two-step reaction scheme involving a 3-amino-1,2,4-triazole intermediate, and its structure was unequivocally determined. However, in contrast to the natural product, the synthetic essramycin (1) did not display any antibacterial activity.
