Abstract
Inventia se refera la un procedeu pentru prepararea unor derivati dispiranici cu formula generala I: (vezi formula) în care R este o grupa alchil cu 1...5 atomi de carbon, fenil sau fenil substituit cu halogen, metoxi sau aminoacetil, constînd din tratarea tetrahidro-1-tia-piran-4-onei cu 1-aminometil-1-ciclohexanol, la temperatura de reflux, în solvent ce formeaza azeotrop cu apa si în prezenta de catalizator, dupa care 7-oxa-11-tia-14-azadispiro-[5,1,5,2] pentadecanul format se acileaza, la temperatura de reflux, în prezenta de acceptor de acid, procedeu în care, în scopul maririi randamentului, reactia în prima faza de formare a bazei libere, are loc în toluen sau xilen ca solvent si în prezenta acetatului de amoniu drept catalizator, cupa care acilarea se realizeaza prin tratare cu o clorura acida cu formula RCOC1, în care R are semnificatiile de mai sus, într-o hidrocarbura alifatica inferioara clorurata ca solvent si a unei trialchilamine ca acceptor de acid.
