Mild methods for conducting Knorr chemistry with β-ketonitriles were developed. This enabled the preparation of 4-cyano-penta-substituted pyrroles and gave access to α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor potentiators for biological evaluation. In addition, a series of alkyl and aryl β-ketonitriles were employed in Knorr cyclizations to probe steric tolerance and the possibility
开发了温和的方法来进行β-乙腈的克诺尔化学反应。这使得可以制备4-氰基-戊基取代的吡咯,并可以使用α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(AMPA)受体增强剂进行生物学评估。另外,在克诺尔环化反应中使用了一系列烷基和芳基β-酮腈,以探讨空间耐受性以及通过克诺尔化学方法直接引入芳香族部分的可能性。
