amino acids and peptides 3 and 5-8 were synthesized and their thermal reactivity towards Bergman cyclization studied and compared with the earlier reported amino acid 4, which demonstrated, for the first time, the effect of H-bonding and electrostatic interactions in lowering the activation energy of Bergman cyclization.
合成了新的烯二炔基氨基酸以及肽3和5-8,并研究了它们对Bergman环化的热反应性,并将其与较早报道的氨基酸4进行了比较,这首次证明了H键和静电相互作用在降低氨基酸含量方面的作用。 Bergman环化的活化能。
