Abstract

Se da a conocer un método para preparar una (+)-calanolida A, un inhibidor potente de la transcriptasa inversa del HIV, a partir del cromeno (4). También se suministran productos intermedios utiles para preparar la (+)- calanolida A y sus derivados. De acuerdo con el método descrito, el producto intermedio de cromeno (4) se hace reaccionar con el acetaldehído-dietil-acetal o el peraldehído, en la presencia de un catalizador ácido, con calentamiento, o una reaccion de dos etapas, que incluye una reaccion del aldol con el acetaldehído y la ciclizacion o bajo condiciones ácidas o bajo las condiciones neutrales de Mitsunobu, para producir la cromanona (7). La reduccion de la cromanona (7) con el borohidruro de sodio, en la presencia del tricloruro de cerio, produjo la (+)-calanolida A. También se da a conocer un método para resolver la (+)-calanolida A en sus formas activas opticamente, por medio de un sistema de cromatografía HPLC quiral o por la acilacion enzimática e hidrolisis. Finalmente, se suministra un método para tratar o prevenir infecciones virales, con el uso de la (+)-calanolida o la (-)-calanolida.
