Using the Passerini and Ugi reactions as representative tests, the utility of several alpha-substituted ketones R-CO-CH(2)-X (X = sulfonyloxy, acyloxy, azido, halo, hydroxy, and sulfonyl) in isonitrile-based multicomponent reactions was explored. In a relative rate study (R = PhCH(2)CH(2)), each of the alpha-substituted ketones underwent Passerini condensation more rapidly than the parent ketone. Short
使用Passerini和Ugi反应作为代表性测试,在基于异腈的多组分反应中使用几种α-取代的酮R-CO-CH(2)-X(X =磺酰氧基,酰氧基,叠氮基,卤素,羟基和磺酰基)被探索了。在相对速率研究中(R = PhCH(2)CH(2)),每个α-取代的酮比亲代酮经历Passerini缩合的速度更快。开发了短而高度收敛的恶唑啉,β-内酰胺,二-O-酰基甘油酰胺和其他分子框架的途径。
