Abstract

PROCEDIMIENTO DE PREPARACION DE DERIVADOS RACEMICOS U OPTICAMENTE ACTIVOS DE ESTER DE ACIDO APOVINCAMINICO, DE FORMULA (I), EN QUE R1 Y R2 SON UN GRUPO ALCOHILO DE 1 A 6 CARBONOS. UN DERIVADO DE 9- Y/O 10- Y/O 11-HALO-14-OXO-15-HIDROXIIMINO-E-HOMOEBURNANO RACEMICO U OPTICAMENTE ACTIVO DE FORMULA (II), DONDE EL HALOGENO X PUEDE TOMAR LA POSICION A, B O C, SE HACE REACCIONAR CON UN ALCANOL DE FORMULA (III) Y CON UN ACIDO DESHIDRATANTE CONCENTRADO. EL PRODUCTO OBTENIDO SE REDUCE SELECTIVAMENTE SOBRE EL ANILLO AROMATICO, CON HIDROGENO ACTIVADO CATALITICAMENTE, EN UN DISOLVENTE INERTE. OPCIONALMENTE SE PURIFICA EL PRODUCTO POR RECRISTALIZACION. SE USAN COMO AGENTES VASODILATADORES CEREBRALES. *FORMULA*
