Photochemical Transformations of Chalcone-Vitamin E Hybrids
Abstract. Chalcone-vitamin E hybrids 6’-O-tosyl-3,4,5-trimethoxy-δ-tocopherol-chalcone (1), 3,4,5-trimethoxy-δ-tocopherol-chalcone (2), 6’-O-tosyl-3,4,5-trimethoxy-δ-tocopherol-retrochalcone (3) and 3,4,5-trimethoxy-δ-tocopherol-retrochalcone (4) were synthesized as part of a search for new biological activities in these types of derivatives. We report herein on the photoisomerization products of hybrids 1-4, and the effects of the solvent and substitution patterns in producing secondary products such as flavanone 6, 3-deoxyanthocyanidin 8, and hemiketal 10. Photochemically-induced changes are considered important since structural modifications and/or the presence of additional products can affect the biological activity of this type of semisynthetic hybrids.   Resumen. Los híbridos de chalcona-vitamina E, 6’-O-tosil-3,4,5-trimetoxi-δ-tocoferol-chalcona (1), 3,4,5-trimetoxi-δ-tocoferol-chalcona (2), 6’-O-tosil-3,4,5-trimetoxi-δ-tocoferol-retrochalcona (3) y 3,4,5-trimetoxi-δ-tocoferol-retrochalcona (4), fueron sintetizados como parte de la búsqueda de nuevos perfiles de actividad biológica para este tipo de derivados.

Los cambios fotoinducidos son considerados de gran importancia debido a que la modificación en la estructura y/o la presencia de productos adicionales puede afectar la actividad biológica de este tipo de híbridos semisintéticos.

期刊介绍: The Journal of the Mexican Chemical Society (J. Mex. Chem. Soc.) is a scientific, blind, peer reviewed, and open access, free of charge publication that covers all areas of chemistry and its sub-disciplines (i.e. medicinal chemistry, natural products, electrochemistry, material science, computational chemistry, organic chemistry, bionirganic chemistry, etc). It is devoted to facilitating the worldwide advancement of our understanding of chemistry. It will primarily publish original contributions of research in all branches of the theory and practice of chemistry in its broadest context as well as critical reviews in active areas of chemical research where the author has published significant contribution. The J. Mex. Chem. Soc. is a quarterly publication which language of submission and publication is English. To be suitable for publication in J. Mex. Chem. Soc., manuscripts must describe novel aspects of chemistry, high quality of results and discussion an excellent bibliographic support, and contribute to the development of the field. Routine or incremental work are not suitable for publication in J. Mex. Chem. Soc. Authors are encouraged to send contributions in electronic form. Our online submission system guides you stepwise through the process of entering your article details and uploading your files.
