Synthetic approaches for new 2,5-disubstituted-1,3-thiazolidines are described. Steric and electronic effects of the N-substituent of the thiazolidine ring represent the major parameter in the rearrangement process. The nmr studies demonstrate that N-unsubstituted 2,5-disubstituted-1,3-thiazolidines exist as epimeric mixture, while the corresponding N-acetylated analogues exist as a conformer mixture
描述了用于新的2,5-二取代的1,3-噻唑烷的合成方法。噻唑烷环的N-取代基的立体和电子效应是重排过程中的主要参数。核磁共振研究表明,N-未取代的2,5-二取代-1,3-噻唑烷以差向异构体混合物形式存在,而相应的N-乙酰化类似物以构象异构体混合物形式存在。
