Abstract

Procedimiento para la preparación de compuestos *** ver imagen 01 en donde se hace reaccionar un o.hidroxibenzaldehido hidroxi substituido mediante fusión con epiclorhidrina o epibromhidrina y se convierte el (3-cloro) o (3-bromo-2-hidroxi-propoxi)-2-hidroxibenzaldehido así obtenido en el epoxi correspondiente, haciéndose reaccionar este último mediante fusión con el o.hidroxibenzaldehido hidroxi substituido de partida, caracterizado porque se cicliza el 1,3-bis-(formal-hidroxifenoxi)-2-hidroxipropano así formado, apropiadamente protegido opcionalmente.
