Diels-Alder Reactions of Pinacol Alkenylboronates: An experimental and theoretical study
(Royal Society of Chemistry, 2014-08)
We have studied the Diels-Alder reactions of pinacol alkenylboronates with cyclopentadiene under two different sets of conditions: thermal heating at 170 C in a pressure tube and with catalytic TFA (5 mol%) at 80 °C. Yields ...
Studies on chemo- and diastereo-selectivity of the Diels-Alder reactions of sulfinyltoluquinones with cyclopentadiene
(NATL RESEARCH COUNCIL CANADA-N R C RESEARCH PRESS, 2009)
Sulfinyltoluquinones (2a-2c) were submitted to thermal or catalyzed [4+2] cycloaddition reactions with cyclopentadiene. For p-tolylsulfinyltoluquinones (2b) and (2c), almost complete C2-C3-chemo- and unlike-diastereoselectivity ...
Understanding the influence of Lewis acids in the regioselectivity of the Diels–Alder reactions of 2-methoxy-5-methyl-1,4-benzoquinone: A DFT study
(Elsevier B.V., 2009-03-03)
The mechanisms of the Diels–Alder (DA) reactions of 2-methoxy-5-methyl-1,4-benzoquinone 1 with 2-
methyl-1,3-butadiene 2, in the absence and in the presence of LA catalysts, have been studied using the
DFT method at the ...
