[figure: see text] beta-Lactams were prepared on solid phase starting from serine, threonine, or other beta-hydroxyacids derived from naturally occurring amino acids and a resin bound hydroxylamine. The ring closure was carried out under Mitsunobu conditions. The amino group present on the beta-lactam was used to assemble a short peptide. After a reductive cleavage with Sml2, beta-lactam-containing
[图:见正文]β-内酰胺是从丝氨酸,苏氨酸或其他衍生自天然氨基酸和树脂结合的羟胺的β-羟酸开始,以固相制备的。闭环在Mitsunobu条件下进行。β-内酰胺上存在的氨基用于组装短肽。在用Sml2还原性切割后,获得了含β-内酰胺的肽。
