标题:氟化烯烃内酰胺:以氨基酸为例--制备和机理研究
摘要:在此,我们报告了具有单氟乙烯基部分的氨基酸类似物的合成.有趣的是,我们发现所得产物的环化在所有情况下都很容易进行.在该反应阶段之前没有观测到环化过程,并且以前没有描述过衍生自苯丙氨酸,缬氨酸,丙氨酸的这种氟化内酰胺.

标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.
