S. Rudershausen et al., INTRAMOLECULAR MACROCYCLIZATION OF BIS(5-METHYLTHIO-1,2-DITHIOLE-3-THIONE) WITH TRIETHYL PHOSPHITE - A STEREOSELECTIVE ROUTE TO MACROCYCLIC(Z)-THIOXODESAURINES, Chemical communications, (16), 1998, pp. 1653-1654
Intramolecular macrocyclizations of [oligo(oxyethylene)-ethylenedithio
]bridged bis(5-methylthio-1,2-dithiole-3-thione)s 5a and b with P(OEt)
(3) in p-xylene furnished the macrocyclic thioxodesaurin (Z)-6, thioxo
desaurin (E)-7 and 1,3-dithiafulvene (E)-8, respectively.
