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.
采用串联反应过程形成了TAN-1057 A和B二肽抗生素的四氢吡咯啉酮核心。氨对去氨基丙氨酸衍生物的迈克尔加成,随后S-甲基异硫脲的分子内取代,在一步中组装了四氢吡咯啉酮。
