ΧΡΗΣΕΙΣ ΤΩΝ ΣΟΥΛΦΙΔΙΩΝ ΣΤΗΝ ΟΡΓΑΝΙΚΗ ΣΥΝΘΕΣΗ. 1) ΜΕΘΟΔΟΛΟΓΙΑ ΣΧΗΜΑΤΙΣΜΟΥ ΑΛΛΥΛΙΚΩΝ ΚΑΡΒΑΝΙΟΝΤΩΝ ΜΕΡΙΚΩΣ ΕΝΣΩΜΑΤΩΜΕΝΩΝ ΣΕ ΙΣΟΚΥΚΛΙΚΟΥΣ ΔΑΚΤΥΛΙΟΥΣ 2) ΕΠΙΜΗΚΥΝΣΗ ΑΛΚΥΛΟΜΑΔΟΣ ΟΡΓΑΝΟΛΙΘΙΚΩΝ ΕΝΩΣΕΩΝ

THIS RESEARCH WORK HAS TWO PARTS. IN THE FIRST PART A NEW METHOD FOR THE FORMATION OF ALLYLIC CARBANIONS WAS DEVELOPED, TWO CARBONS OF WHICH TAKE PART IN ISOCYCLIC RINGS. METHYL-PHENYL SULFIDE WAS USED FOR THIS PURPOSE. COUPLING OF THE LITHIATED SULFIDE WITH A NUMBER OF ALIPHATIC CYCLOKETONES LED TO CARBINOLS, WHICH WERE SELECTIVELY DEHYDRATED TO FORM ENDO OLEFINS. CLEARAGE OF THE PHS-GROUP OF THE OLEFINS, FOLLOWED BY CARBON DIOXIDE ATTACK, RESULTED IN STEREOSELECTIVE FORMATION OF ISOMERIC CARBOXYLIC ACIDS HAVING EXO OR ENDO DOUBLE BOND, DEPENDINGON THE SIZE OF THE CYCLIC RINGS. IN THE SECOND PART, A NEW METHOD FOR THE ALIPHATIC CHAIN ELONGATION OF ORGANOLITHIUM COMPOUNDS WAS DEVELOPED. THE STARTING MATERIALS WERE PHS-SUBSTITUTED ALKYLHALIDES. THE ELONGATION WAS SUCCEEDED VIA "HETEROCUPRATES".
