The reaction of dichloropyrazines with a dithiane anion gave isomers of the expected formylated chloropyrazines after deprotection with methyl iodide. A tele-substitution mechanism accounts for these observations and is supported by deuterium labelling studies.

action by inhibiting tubulin polymerization and was effective against P-glycoprotein-mediated multiple drug resistance and taxol resistance. In vivo, 60c exhibited a strong inhibitory effect on tumor growth and metastasis in a taxol-resistant A375/TxR xenograft model without obvious toxicity. Collectively, this work showed that 60c is a promising lead compound for further development as a potential anticancer
