The use of a dipeptide library as the source of a micromolar chemical leadcompound for the human tachykinin NK3 receptor is described. The screening of a dipeptide library through a cloned human NK3 receptor binding assay resulted in the identification of Boc(S)Phe(S)PheNH2 (1), which has subsequently been developed, following a 'peptoid' design strategy, into a series of high-affinity NK3 receptor
efficient primary-amine-directed, palladium-catalyzed C−H halogenation (X=I, Br, Cl) of phenylalanine derivatives is reported on a range of quaternary amino acid (AA) derivatives thanks to suitable conditions employing trifluoroacetic acid as additive. The extension of this original native functionality-directed ortho-selective halogenation was even demonstrated with the more challenging native phenylalanine
由于采用三氟乙酸作为添加剂的合适条件,在一系列季氨基酸 (AA) 衍生物上报道了苯丙氨酸衍生物的有效伯胺导向、钯催化的 C−H 卤化 (X=I, Br, Cl)。这种原始的天然官能团导向的邻位选择性卤化的扩展甚至用更具挑战性的天然苯丙氨酸作为叔 AA 得到了证明。
