Abstract
Inventia se refera la un procedeu pentru prepararea unor derivati de piranona, hipocolesterolemici sau hipolipemici care prezinta formula generala I: (vezi form. in desc.) în care E reprezinta -CH2-CH2-sau -CH=CH-, R1 reprezinta un radical alchil inferior sau un atom de halogen în pozitia 2, R2 este un radical alchil inferior sau un atom de halogen în pozitia 4, R3 reprezinta un radical halofenilalcoxi cu 1...3 atomi de carbon halofenoxi sau fenil substituit cu halohen si/sau alchil inferior în pozitia 6, plecînd de la o aldehida cu formula generala II: (vezi form. in desc.) care se supune reactiei cu dianionul acidului acetoacetic din esterul alchilic al acidului acetoacetic obtinîndu-se un compus cu formula generala III, urmata de tratarea cu NaBH4 într-un alcanol inferior la sau sub temoperatura camerei, dupa care compusul obtinut poate fi saponificat, lactonizat si apot fi reduse legaturile duble în grupa E si separati anatiomerii prin metode cunoscute.
