Reação de β-dimetilaminovinil cetonas com hidroxilamina: regioquímica de formação de 4,5-diidroisoxazóis e de isoxazóis
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2005-07-28)
The regiochemistry study of the formation of a series of aryl-, heteraryl- and haloalkyl-substituted isoxazoles from the reaction of β-dimethylaminovinyl ketones and
hydroxylamine is reported. The precursors β-imethylaminovinyl ...
Hydroalumination of Thioacetylenes: A Versatile Generation and Reactions of -Aluminate Sulfides Intermediates
(TAYLOR & FRANCIS INC, 2008)
Hydroalumination of thioacetylenes using DIBAL-H and lithium di-(isobutyl)-n-(butyl)-aluminate hydride (Zweifel`s reagent), followed by addition of water, furnished exclusively the (Z)- and (E)-vinyl sulfides, respectively. ...

DFT calculations induced a regiochemical outcome revision of the Diels-Alder reaction between levoglucosenone and isoprene
(Pergamon-Elsevier Science Ltd, 2011-06)
An appealing inversion in the regiochemical outcome of Diels-Alder reactions between levoglucosenone (1) and its α-bromo derivative (5) with isoprene (2) was studied computationally. Based on different DFT calculations we ...
