新型螺杂环化合物的原子经济性,化学,区域和立体选择性合成与晶体结构
Highly Atom Economic, Chemo-, Regio-and Stereoselective Synthesis and Crystal Structure of Novel Spiro-Cyclopentanone
he 1,3-dipolar cycloaddition of azomethine ylides derived from acenaphthenequinone and α-amino acid(sarcosine) to a series of 2,5-bis(fluorobenzylidene)cyclopentanones afforded novel spiro-cyclopentanone-pyrrolizines chemo-, regio- and stereoselectively in quantitative yields (95–96%). The crystal structure of one compound containing bis(2,6-difluorobenzyl) (2b) is described. The cyclopentane rings in 2b have an envelope conformation.
