The terminally protected, linear, homo-β-peptides Boc-[(R)-β2,2-HBin]n-OMe (n = 2–6) as well as the cyclic homo-β-peptides c[(R)-β2,2-HBin]3 and c[(S)-β2,2-HBin]4, all derived from the 2′,1′:1,2;1″,2″:3,4-dinaphthcyclohepta-1,3-diene-6-aminomethyl-6-carboxylic acid residue β2,2-HBin possessing only axial chirality, have been synthesized in solution by the EDC/AtOH coupling method for chain elongation
的末端保护的,直链的,HOMO-β肽的Boc - [([R)-β 2,2 -HBin] Ñ -OMe(Ñ = 2-6)以及作为环状HOMO-β肽C [([R ) -β 2,2 -HBin] 3和c [(小号)-β 2,2 -HBin] 4,所有从2',1'导出:1,2; 1“,2”:3,4-dinaphthcyclohepta -1,3-二烯-6-氨基甲基-6-羧酸残基β2,2-HBin仅具有轴向手性,已在溶液中通过EDC / AtOH偶联方法进行链延长和五氟苯基酯环化合成。构象分析表明溶液中线性低聚物会同时发生不同的分子内氢键形式。
