Synthesis and stereochemistry of bis(dithiacrown ether) and dodecylthio substituted (E)-thiodesaurines
摘要:
Reductive dimerization of dodecylthio substituted 1,2-dithiole-3-thiones 6a-b and trithion-dithiacrown ethers 10a-c with triethyl phosphite furnished bis- and tetrakis (dodecylthio), and bis(dithiacrown ether) substituted thiodesaurines (E)-11a-b and (E)-12a-c. The stereochemistry of bis(dithia[15]crown-5)-thiodesaurine (E)-12b has been determined by X-ray crystallographic analysis.
