CO from Mo(CO)6 with an aminoacidamide nucleophile is reported. Furthermore, a microwave-assisted protocol for the direct C-5 arylation of 1-benzyl-1H-imidazole and a regioselective C-4 iodination method to acquire starting material for our aminocarbonylation are presented. The method can be used to prepare imidazole based peptidomimetics, herein exemplified by the synthesis of constrained H-Phe-Phe-NH2
一个简单的和一种适宜的方法制备5-芳基-1-苄基- 1 H ^ -咪唑-4-甲酰胺由5-芳基4-碘- 1的氨基羰基化ħ -咪唑使用易地从沫生成CO的(CO )报道了具有氨基酸酰胺亲核试剂的6。此外,提出了一种用于微波辅助的1-苄基-1 H-咪唑直接C-5芳基化的方案,以及一种区域选择性的C-4碘化方法,以获取用于我们氨基羰基化的原料。该方法可用于制备基于咪唑的拟肽,在此以受限的H-Phe-Phe-NH 2类似物的合成为例。
