Magalhães Química Leguminosae deoxybenzoin Deguelia hatschbachii In this paper we describe the synthesis of 2´,4´-dimethoxy-8-(propyl-2-one)-deoxybenzoin, anew compound employed as a model for the comparison with the respective spectral data for 6,4-dihydroxy-3-(3,3- dimethylallyl)-2",2"-dimethylchromene(5",6":5,4)-2-methoxy-8-(propyl-2-one)deoxybenzoin, recently isolated from Deguelia hatschbachii A.M.G. Azevedo. Both compounds have apropyl-2-one group attached to C-8 of the deoxybenzoin skeleton, for which there is no precedent inthe literature. The Friedel-Crafts reaction of 1,3-dimethoxybenzene with phenylacetyl chloride furnished2´,4´-dimethoxydeoxybenzoin, that after reaction with allyl bromide gave 2´,4´-dimethoxy-8-(allyl)-deoxybenzoin. Wacker oxidation gave the desired model compound in 15% overall yield. The correspondingspectral data reinforced the structure previously determined for the natural product. 2005 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42930106 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.1 Vol.30 |
