Abstract
Procedeu pentru prepararea unor derivati de oleandomicina cu formula generala I: (vezi formula) în care simbolul X reprezinta radicalul mai mic C=CH2, R, R1 si R2 reprezinta un atom de hidrogen sau un radical alchil cu 2...3 atomi de carbon, caracterizat prin aceea ca un compus, avînd formula generala II: (vezi formula) în care R, R1 si R2 au semnificatiile sus-mentionate, se aduce în reactie, sub atomsfera de CO2, la temperatura camerei, cu o sare anorganica, care contine ionul unui metal, si anume, Cr la puterea 2+, Ti la 3+ sau V la 2+, într-un solvent inert în conditiile reactiei, de preferinta acetona, alcanoli inferiori, tetrahidrofuran, dupa care, în compusul obtinut poate fi eventual, înlocuit substituentul R2 cu radicali trifluoracetil, sililtrialchil inferior sau se prepara o sare de aditie cu un acid, prin metode cunoscute.
