Abstract
Similar yet different: A one-step regio- and diastereoselective synthesis of three new bis(pyrrolidine)[60]fullerenes, one cis-1 and two unprecedented cis-2 diastereoisomers, is reported. The compounds are easily purified using simple chromatographic techniques, and were fully characterized by spectroscopic techniques and X-ray crystallography. A mechanism for the isomeric conversion observed is proposed.
摘要
类似但又不同
一步区域和立体选择性合成了三种新型双（吡咯烷）[60]富勒烯，一种顺式-1 和两种前所未有的顺式-2 非对映异构体。这些化合物可以使用简单的色谱技术进行轻松纯化，并通过光谱技术和 X 射线晶体学进行了全面表征。提出了观察到的异构体转化的机制。
