TL;DR: In this article, a series of twelve 3-aryl[alkyl]-5-hydroxy-5-trichloromethyl-4, 5-dihydro-1H-pyrazole-1-carboxyamides and analogous 1-thiocarboxy-amides is reported.

TL;DR: In this paper, the synthesis of 3-aryl[alkyl]-5-hydroxy-5-trifluoromethyl-4,5-dihydro-1H-1-pyrazolethiocarboxyamides (2a−g) from the direct cyclocondensation reaction of b-alkoxyvinyl trifluorsyl ketones with thiosemicarbazide in methanol, under mild conditions, is reported.

TL;DR: In this article, a method to obtain a new series of 2-trichloromethyl-4-aryl-3H-1,5-benzodiazepines from the reaction of β-methoxyvinyl trichlormethyl ketones derived from acetals and o-phenylenediamine is reported.

TL;DR: In this article, the synthesis of a series of 6-aryl(5-methyl)-4-trifluoromethyl-2(1H)-pyrimidinones from the reaction of 4-aryl-4-methoxy-1, 1,1,1-, trifluoro-3-buten-2-ones with urea in the presence of hydrochloric acid was reported.

TL;DR: Alem das avaliacoes entre genotipos, a utilizacao de tecnicas multivariadas possibilita restringirem-se os erros, principalmente quanto a diversidade genetica, podendo-se, assim, prever combinacoes com maior efeito heterotico.
