We have developed second-generation monomers 1 and 2 and improved conditions for rapidly and simultaneously closing multiple diketopiperazines on solid support. These new conditions involve either the microwave heating of a suspension of solid-supported amino-tetrafluoropropyl esters in acetic acid/triethylamine catalyst solution or continuous flow of catalyst solution through the resin, heated in
我们已经开发出第二代单体1和2,并改善了条件,可以快速同时封闭固体载体上的多种二酮哌嗪。这些新条件包括在加热流动池设备中微波加热固体负载的氨基四氟丙基酯在乙酸/三乙胺催化剂溶液中的悬浮液,或使催化剂溶液连续流过树脂。我们证明,新的单体1和2可以与新的条件轻松地合成以前无法获得的杂和同螺形梯形低聚物3和4等。
