Abstract
Invenţia se referă la procedeele de obţinere a izotiocianatochalconelor, care pot fi utilizate în calitate de precursori pentru sinteza unor chalcone de uz medicinal sau cosmetic.Procedeul revendicat include condensarea l,l-dimetil-3-(3- sau 4-acetilfenil)tioureelor cu aldehide aromatice substituite, cu obţinerea N,N-dimetiltioureidochalconelor care se dezaminează într-un solvent inert la încălzire cu acizi minerali (H2SO4, HCl în dioxan) sau cu anhidridă acetică (în benzen sau toluen), luaţi, respectiv, în raport echimolar.
