Synthesis of the Bycroft−Gowland Structure of Micrococcin P1
摘要:
[GRAPHICS]We describe the chemical synthesis of the accepted structure of micrococcin P1, a member of the thiostrepton group of antibiotics, and we show that this architecture does not correspond to that of the natural product. Methods developed during the present study should greatly facilitate ongoing efforts centering on the determination of the actual structure of microccin P1, in addition to being applicable to the synthesis of more complex thiostrepton congeners.

Fifty years after the discovery of the thiopeptide antibiotic micrococcinP1, the constitutional and stereochemical uncertainties concerning its structure have been lifted with its totalsynthesis and absolute stereochemicalassignment (see picture).
