Synthesis of New 8-Phenyl[1,2]dithiolo[1,5-b]naphtho[2,1-d][1,2]dithiole-10-SIV, 2,5-Diphenyl-3,4-dihydro-1,6,6a-trithia(6a-SIV)cyclopenta[cd]pentalene and 2,6-Diphenyl-4,5-dihydro-3H-[1,2]dithiolo[4,5,1-hi][1,2]benzodithiole-8-SIV Derivatives
the pharmacological screening of a number of pyran-4-ones their synthesis by cyclization with sulphuric acid of the corresponding 1,3,5-triketones has been carried out with high yields. In the course of preparation of the latter the reaction of 2-acetyltetralone with some esters of benzoic acid derivatives has been studied and in particular, for a number of them, an interesting nucleophilic substitution
