Assembly of the TAN-1057 A/B heterocycle from a dehydroalanine precursor

Lin,Ganesan

, p. 2127 - 2130 (2007/10/03)

A tandem reaction process was used to form the tetrahydropyrimidinone core of the TAN-1057 A and B dipeptide antibiotics. Michael addition of ammonia to a dehydroalanine derivative, followed by intramolecular displacement of an S-methylisothiourea assembles the tetrahydropyrimidinone in one-step.
