Synthesis of 2H-naphtho[2,3-b]thiopyranoquinones and density functional study for the Diels-Alder reaction of a benzothiopyranoquinone
(PERGAMON-ELSEVIER SCIENCE LTD, 2000)
The synthesis of benzothiopyranoquinone (6) in three step from benzothiopyran (3) is described. Diels-Alder reaction of quinone (6) with 1,3-pentadiene (7), cyclopentadiene, 1-methoxy-1,3-cyclohexadiene (11) and ...
Remote regio- and stereocontrol by the sulfinyl group: Diels-Alder reaction of sulfinyl dienols and 8,8-dimethylnaphthalene-1,4,5(8H)-trione
(2013)
Diels-Alder cycloaddition of 8,8-dimethylnaphthalene-1,4,5(8H)-trione with diastereomeric hydroxysulfinyldienes proceeded with high yields and good π-facial and regioselectivities. The hydroxysulfoxide moiety controls the ...
Estratégias sintéticas para a preparação de novos fotossensibilizadores do tipo ftalocianinas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2013-02-28)
In this work some studies about the synthesis of a new Znphthalocyanine derivative containing 8 tert-butyl groups on peripheral positions were performed. In order to obtain this compound, a new monomeric unit were synthesized ...

Theoretical and experimental study of the reaction system and DA cycloaddition products of N-benzyl-1-(furan-2-yl)methanamine (1a), and N-benzyl-N-(furan-2-ylmethyl)acetamide (1b) was developed using maleic anhydride (AnM) ...
1,3-Dipolar cycloaddition reactions of azomethine ylides with a cellulose-derived chiral enone. A novel route for organocatalysts development
(American Chemical Society, 2012-05)
Cellulose-derived chiral pyrrolidines were synthesized in excellent yields, regioselectivities, and stereoselectivities via a 1,3-dipolar cycloaddition reaction between levoglucosenone and azomethine ylides. An unprecedented ...
Studies on quinones. Part 44: Novel angucyclinone N-heterocyclic analogues endowed with antitumoral activity
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In the search for new potentially anticancer drugs, series of angucyclinone aza-analogues containing pyridine and pyridopyridazine rings have been designed and synthesized by a highly efficient sequence involving a one-pot ...
