Mechanistic Insights in the Mode of Action of Bifunctional Pyrrolidine-Squaramide-derived Organocatalysts
(Wiley-VCH, 2016)
The modes of catalytic action of three squaramide-derived
bifunctional organocatalysts have been investigated using DFT
methods. The [5+2] cycloaddition between oxidopyrilium ylides and
enals has been used as model ...
