rosin-derived amine thiourea catalysts were designed and synthesized. The doubly stereocontrolled asymmetric addition of a variety of 1,3-dicarbonyl compounds to nitroalkenes was investigated. These rosin-derived chiral thioureas have been shown to serve as effective catalysts for this double-sterecontrolled organocatalytic process by the investigation of the efficacy of the thiourea catalysts in comparison with
从可商购的天然松香衍生物开始,设计并合成了一类双官能松香衍生的胺硫脲催化剂。研究了将多种1,3-二羰基化合物双立体控制的不对称加成到硝基烯烃中。通过研究硫脲催化剂与已报道的其他硫脲催化剂的功效,已证明这些松香衍生的手性硫脲可作为该双酯控制的有机催化方法的有效催化剂。另外,这些手性硫脲配体容易获得。此外,
