Abstract

SE REFIERE A UN PROCESO PARA LA PREPARACION DE 7O-ESTEROIDES DE FORMULA I DONDE R1 ES H, METIL, ENTRE OTROS; R2 ES (CH2)nOH DONDE n ES 0-2: POR UNA ADICION DE 1,6-CONJUGADO MEDIADO CON COBRE DE REACTIVO DE GRIGNARD CH3MgX DONDE X ES HALOGENO, PARA LOS 3-CETOESTEROIDES 4,6-NO SATURADO DE FORMULA II, COMPRENDIENDO PROTECCION AL GRUPO HIDROXI DEL ESTEROIDE DE FORMULA II CON UN GRUPO DE TRIALQUILSILIL SEGUIDO POR EL TRATAMIENTO DEL ESTEROIDE PROTEGIDO DE OH CON EL REACTIVO DE GRIGNARD. EL SOLVENTE DE LA REACCION ES TETRAHIDROFURANO, ETER DIETIL; LA CONCENTRACION DEL ESTEROIDE AL REACTIVO DE GRIGNARD ES DE 1:1 A 1:7 Y SE USA ACETATO DE COBRE (II) DEL CATALIZADOR DE COBRE O CLORURO DE COBRE (II) Y LA REACCION SE LLEVA A -78°C A O°C. EL COMPUESTO ESTEROIDE ES 21-HIDROXI-19-NORPREGN-4,6-DIEN-3-ONA.
