1.General approaches involve the nucleophilic cycloalkylation, carbenoids addition of certain amino acid derivatives and derivatization from simple cyclopropane compounds.

1.制备方法简单氨基酸衍生物的亲核环烷基、类卡宾加成以及简单环烷合物的衍生合成等。

2.Based on these results and the ESI-MS data, the mechanism of sulfoxidation was proposed to be intramolecular nucleophilic oxygen transfer to a coordinated sulfide.

2.基于这些结果和电喷雾质谱(ESI-MS)数据，反应的机理推测为分子内亲核氧转移到络合的硫醚底物上。
