Abstract

ZANATTA, Nilo et al. Synthesis of N-substituted 6-trifluoromethyl-1,3-oxazinanes. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.6a, pp. 1255-1261. ISSN 1678-4790.  http://dx.doi.org/10.1590/S0103-50532005000700025.

Este trabalho apresenta a síntese de duas novas séries de 6-trifluormetil-1,3-oxazinanas N-substituídas e 6-trifluormetil-1,3-oxazinan-2-onas N-substituídas, a partir da ciclização de 4-ilamino-1,1,1-trifluor-butan-2-óis com formaldeído e trifosgênio, respectivamente. Os 4-ilamino-1,1,1-trifluor-butan-2-óis foram obtidos através da reação de redução dos precursores 4-ilamino-1,1,1-trifluor-but-3-en-2-onas, utilizando hidrogênio e 10% Pd/C, com bons rendimentos.

Keywords : g-amino alcohols; b-enamino ketones; 1,3-oxazinanes; 1,3-oxazinan-2-ones; 1,3-oxazines.
