A novel solid phase synthesis of tertiary amines involving iodide-induced cleavage of the NO bond of resin bound alkoxyammonium intermediates is described. The quaternary intermediates were assembled via sequential reductive aminations followed by alkylation. Cleavage from the solid support was induced by iodide ion or base, to afford the target tertiary amines in excellent purity.
描述了叔胺的新型固相合成,该合成涉及碘引起的树脂结合的烷氧基铵中间体的N = O键的裂解。通过顺序还原胺化然后进行烷基化来组装季中间体。通过碘离子或碱诱导从固相支持物上的裂解,从而以优异的纯度提供目标叔胺。
