Spectroscopic study of stepwise gossypol sulfonylation with tosyl chloride in the presence of 4-methoxypyridine N-oxide and triethylamine

Oleksii M. Dykun et al.

Summary: The sulfonylation of gossypol was conducted with stepwise increase of tosyl chloride content in the presence of 4-methoxypyridine N-oxide and triethylamine. It was found that 4-methoxypyridine N-oxide is a more effective catalyst compared to triethylamine, allowing selective tosylation of gossypol to 7,7'-ditosyloxygossypol. The study also investigated the structure and tautomeric equilibria of the obtained product in dichloromethane, showing that a dilactol tautomeric form is more preferable for 7,7'-ditosyloxygossypol.
