Abstract
Recent studies on the organic synthesis with organosulfur compounds, mostly by B. M. Trost, were reviewed.
The total synthesis of some sesquiterpenes illustrates a new approach to spiroannelation, secoalkylation, and 1, 2-alkylative carbonyl transposition.
Sulfenylation of esters and ketones followed by oxidation and thermolysis leads to the α, β-unsaturated system. A 1, 2-shift of the carbonyl group of esters and ketones is described. A new type of cycloalkanone ring cleavage has been developed. The key step involves an oxidative cleavage with Pb (OAc) 4 and a rearrangement of the sulfur unit. Some other recent advances in this field are described.
