Pseudo-Pericyclic Reactions: Aromatic Compound Derivatives as Electrophiles in Polar Diels-Alder Reactions. An Experimental and Theoretical Study
(The Research Trends Editorial, 2014-11)
The Diels-Alder reaction is considered a pericyclic procces. However, depending of the structure of the diene and the dienophile the nature of this reaction can change. In the last years we have worked with aromatic nitro ...
Influence of the CH/B replacement on the reactivity of boranthrene and related compounds
(American Chemical Society, 2021-10)
The influence of the replacement of CH groups by boron atoms on the reactivity of planar polycyclic aromatic hydrocarbons has been explored by means of computational tools. To this end, [4 + 2]-cycloaddition reactions ...
Synthesis of Phenanthrenol Derivatives Through Polar Diels-Alder Reactions Employing Nitronaphthalenes and (E)-1-(Trimethylsilyloxy)-1,3- butadiene. Theoretical Calculations
(Bentham Science Publishers, 2014-02)
The cycloaddition reactions between nitronaphthalenes and 1-trimethylsilyloxy-1,3-butadiene produce phenantrenol derivatives as principal products. The primary adducts suffer the irreversible lost of nitrous acid and ...
