Abstract

Un procedimiento para preparar una 6ª, 10ª-trans-hexohidrodibenzo[b,d]piran-9-ona de la fórmula general **ver imagen (I)** en dónde R es alquilo de ci2c10, alquenilo de C5-C10, cicloalquilo de C5-C8, o cicloalquenilo de C5-C8, y en donde los átomos de hidrógeno unidos en las posiciones 6ª y 10 están orientados trans uno al otro, cuyo procedimiento está caracterizado por hacer reaccionar un a 6ª,10ª-cis-hexahidrodibenzopiranona que tiene la fórmula anterior, en donde los átomos de hidrógeno unidos en las posiciones 6ª y 10ª están unidos cis uno al otro, con bromuro de aluminio o cloruro de aluminio en un disolvente orgánico no reacctivo a una temperatura de -80ºC a 100ºC, durante de 10 minutos a 6 horas para producir la 6ª,10ª-trans 1-hidroxi-3-sustituido-6,6-dimetil-6,6ª,7,8,10,10ª-hexahidro-9H-dibenzo[b,d] piran-9-ona
