intermediate products for the synthesis of hydroxyethylene dipeptide isosteres. The low stereoselectivity of this reaction can be improved using aldehydes protected with hindered groups. This reaction can be efficiently applied to oligopetide aldehydes. We describe a protocol, for the preparation of peptides containing an hydroxyethylene isostere, which allows a rapid variations of the aminoacid sequence
不同取代的烯丙基溴与N-保护的氨基醛反应,生成用于合成羟乙烯二肽等排体的中间产物。使用受阻基团保护的醛可以改善该反应的低立体选择性。该反应可以有效地应用于寡肽醛。我们描述了一种用于制备含有羟乙烯等排体的肽的方案,该方案可以快速改变氨基酸序列
