- Tautomeric selectivity towards colchicinoids in the tosylation of colchiceine on a heterogeneous, easily removable catalyst.
-
Here is presented an easy, rapid new method of tosylation of compounds containing acidic OH groups, such as tropolones and phenols, on a solid, removable catalyst, Amberlite IRA-400(OH); of special value is the preferential selectivity for the colchiceine
