Description

A new general and efficient method for the one-pot synthesis of (E)-benzylideneflavanones, dibenzospiropyrans and coumarin-3-carbonitriles/carboxamides is achieved through tandem aldol-cyclocondensation of o-hydroxyaryl carbonyl compounds with aryl aldehydes or enolisable ketones or through Knoevenagel reaction by the aid of SiCl4/EtOH at ambient temperature.

Translated Description (Arabic)

يتم تحقيق طريقة عامة وفعالة جديدة لتوليف وعاء واحد من (E) - benzylideneflavanones و dibenzospiropyrans و coumarin -3 - carbonitriles/carboxamides من خلال التكثيف الترادفي لمركبات الكربونيل o - hydroxyaryl مع ألدهيدات الأريل أو الكيتونات القابلة للاندماج أو من خلال تفاعل Knoevenagel بمساعدة SiCl4/EtOH في درجة الحرارة المحيطة.

Translated Description (French)

Une nouvelle méthode générale et efficace pour la synthèse en pot unique de (E)-benzylideneflavanones, de dibenzospiropyrans et de coumarine-3-carbonitriles/carboxamides est obtenue par cyclocondensation aldolique en tandem de composés o-hydroxyarylcarbonyle avec des aldéhydes aryliques ou des cétones énolisables ou par réaction de Knoevenagel à l'aide de SiCl4/EtOH à température ambiante.

Translated Description (Spanish)

Se logra un nuevo método general y eficiente para la síntesis en un solo recipiente de (E) -bencilidenflavanonas, dibenzoespiropiranos y cumarin-3-carbonitrilos/carboxamidas a través de la ciclocondensación aldólica en tándem de compuestos de o-hidroxiarilcarbonilo con arilaldehídos o cetonas enolizables o a través de la reacción de Knoevenagel con la ayuda de SiCl4/EtOH a temperatura ambiente.
