Reactions of aromatic dithiols with diethyl 2-alkyl-2-(oxiran-2-ylmethyl)malonates
摘要:
New sulfur-containing butano-4-lactones were synthesized by reaction of diethyl 2-alkyl-2-(oxiran-2-ylmethyl)malonates with biphenyl-4,4'-dithiol, (biphenyl-4,4'-diyl)dimethanethiol, and (2,4,6-trimethylbenzene- 1,3-diyl)dimethanethiol. Opening of the oxirane ring in the initial ester followed the Krasuskii rule.
