4-trans-disubstituted pyrrolidin-2-ones 11a and 11b, obtained from a Baylis–Hillman adduct, conformationally restricted analogues of both (S)-β-homoserine, 17, and (S)-aspartic acid, 21, were synthesized, respectively, and these compounds are suitable either for introduction in peptidomimetics or for synthesis of novel β-foldamers.
从从Baylis-Hillman加合物获得的手性3,4-反式-双取代的吡咯烷-2--2-酮11a和11b开始,(S)-β-高丝氨酸17和(S)-天冬氨酸的构象受限制的类似物,分别合成了21种化合物,这些化合物既适合于拟肽模拟物的引入,也适合于新型β折叠剂的合成。
