Abstract

Методът е двуетапен и приложим в промишлени условия, като при осъществяването му не се използва вредният бром. Получените съединения намират приложение като хиполипидемични средства в медицината. Съгласно метода за получаване на нафталинови производни с обща формула в която r1, r2, r3, r4, r5, r6, r7 означават низша алкилова група, се осъществява взаимодействие на ди-/низш алкокси/бензалдехид с три-/низш алкокси/бензалдехид ди-низш алкилацетал до -хидроксибензилбензалдехид, който взаимодейства с ацетилендикарбоксилат и по желание полученият продукт се превръща в негова сол.10 претенции
