An efficient synthesis of spiro-fused macrolactams by a multicomponent macrocyclization reaction (MCMR) is reported. The use of highly reactive, transient intermediates in this MCMR permits short reaction times, even at high dilution. The methods employed for this MCMR were first developed as a four-component strategy for the synthesis of β-ketoamide isoxazolines and a new macrocyclization reaction
报道了一种通过多组分大环化反应 (MCMR) 有效合成螺环稠合大内酰胺的方法。在该 MCMR 中使用高反应性、瞬态中间体可以缩短反应时间,即使在高稀释度下也是如此。用于该 MCMR 的方法首先被开发为合成 β-酮酰胺异恶唑啉的四组分策略,并报道了一种新的大环化反应。
