Abstract

PROCEDIMIENTO PARA LA PREPARACION DE DERIVADOS DE 4-HIDROXITETRAHIDROPIRAN 2-ONA. SE REFIERE A LA PREPARACION DE COMPUESTOS DE ESTRUCTURA (I), DONDE A ES HIDROGENO O METILO, E ES UN ENLACE DEL TIPO (II) O (III), R1 ESTA SITUADO EN POSICION ORTO RESPECTO AL RADICAL E Y ES HALOFENILOXI, HALOFENIALCOXI O HALOFENILO, ESPECIALMENTE DONDE HALO ES FLUOR O CLORO; R2 Y R3 SON HALO, ESPECIALMENTE CLORO, EN LAS POSICIONES 4 Y 6. TAMBIEN SE REFIERE A LOS HIDROXIACIDOS RESULTANTES DE LA APERTURA HIDROLITICA DEL ANILLO DE LACTONA, LAS SALES FARMACEUTICAMENTE ACEPTABLES DE LOS HIDROXIACIDOS Y LOS ESTERES ALQUILICOS INFERIORES, FENILICOS Y DIMETILAMINO. PARA SU PREPARACION SE HACE REACCIONAR EL DIANION DE UN ESTER ACETOACETICO CON UN ALDEHIDO DE ESTRUCTURA (IV). SE REDUCE EL GRUPO 3-CETO A GRUPO HIDROXILO. SE SAPONIFICA EL ESTER Y SE LACTONIZA EL CARBOXILO CON EL 6-HIDROXILO. SE UTILIZAN COMO INHIBIDORES DE LA SINTESIS DEL COLESTEROL. *FORMULA*
