2-Amino-5-alkylidene-thiazol-4-ones bearing two diversity points are prepared by a solid-phase strategy exploiting rhodanine as the starting material. Rhodanine is first loaded on bromo-Wang resin, subjected to Knovenagel condensation with aldehydes, and cleaved off the resin in a traceless manner by means of an amine.
通过以罗丹宁为原料的固相策略制备具有两个多样性点的2-氨基-5-亚烷基-噻唑-4-酮。首先将罗丹宁负载在溴旺树脂上,使其与醛进行Knovenagel缩合,然后借助胺以无痕方式将其裂解。
