"PROCESSES FOR THE PREPARATION OF 1,3,5-CYCLEHEXANOTRIONES 2,2,4,4- TETRASSUBSTITUED, FOR THE PREPARATION OF SILYLIC ENOL ESTERS, COMPOUND, USE OF CYCLEBUTANE-1,3-DIONAS". Process for the preparation of 1,3,5-cyclohexanotriones 2,2,4,4-tetra-substituted formula I, by reaction of a cyclobutane-1,3-dione of formula II, with an O or N nucleophile and a silylation reagent, and subsequent acetylation and cyclization.
