标题:萃取相转移催化条件下氢氧根离子的亲核性与碱性的关系
摘要:在相转移催化条件(ptc)下提取氢氧根离子可提供非常强的碱和亲核试剂.H / D交换与1,2,3,4-四氟苯(1)上的亲核芳族取代之间的竞争表明,在萃取相转移催化条件下,氢氧离子作为碱比作为亲核体更有效.

摘要:The invention relates to a new diastereoselective synthesis method for highly modified nucleoside triphosphates with two conjugable groups. The method works in liquid phase with conventional laboratory equipment as used in any chemical laboratory or production. For this, a new chiral P(V) phosphorylation reagent has been designed that allows highly efficient diastereoselective synthesis under mild conditions. Overall, a highly efficient, diastereoselective, high quality, cost-effective synthetic method of modified nucleoside triphosphates has been developed.

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.
