Toward a library synthesis of the natural dipeptide antibiotic TAN 1057 A,B

Aguilar, Nuria,Krueger, Jochen

, p. 469 - 474 (2007/10/03)

The natural dipeptide antibiotic TAN 1057 A,B represents a promising new antibiotic entity. In this communication we report a novel approach for the synthesis of TAN 1057 A,B analogs bearing variations in the β-arginine side chain. This approach involves a combination of liquid and solid phase methods and allows for a library synthesis of analogs of the natural product.
