starting from easily available low-priced precursors are desirable. Two efficient pathways to these structures starting from the 4-methoxylated oxazolidinones 2 and 3, easily accessible from the chiral pool, have been successfully developed. These oxazolidinones can be used as amidoalkylation reagents. Via Sakurai reactions and subsequent intramolecular cyclization, the synthesis of bicyclic pyrrolidines
羟基取代的吡咯烷是氮杂糖的重要结构元素。此类化合物的有效前体是类型 1 的吡咯并恶唑烷酮。需要从容易获得的低价前体开始的短不对称合成。已成功开发了从 4-甲氧基化恶唑烷酮 2 和 3 开始的这些结构的两种有效途径,这些途径很容易从手性池中获得。这些恶唑烷酮可用作酰胺烷基化试剂。通过樱井反应和随后的分子内环化,可以以立体控制的方式合成双环吡咯烷。
