Thesequence is triggered by the regioselective thiolation of indolyl diols followed by an attack of the sulfur insteadof the indole over the activated alkyne. The final compounds are obtained in remarkably high yields and arisefrom simple starting materials such as indolyl acyloins, ethynyl magnesium bromide and thiols.
