标 题 :Synthesis of thalicarpine
发明人：KUPCHAN S MORRIS; LIEPA ANDRIS J
权利人:RESEARCH CORP
摘要:There is disclosed a novel total synthesis of thalicarpine which includes inter alia a total synthesis of hernandaline. The novel process is characterised in utilizing simple and readily available starting materials to form a diaryl ether system which is then condensed with a 3,4-dihydroisoquinolinium salt which is then converted to hernandaline. Hernandaline is reacted with a bicyclic Reissert compound to yield a compound having the thalicarpine skeleton, nascent hydrogen reduction yields Nmonodesmethyl thalicarpine which is methylated.

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.
