A consecutive detosylation/alkylation transformation of tosylated indoles and phenols with alkoxides/alcohols as the alkylation reagents features mild reaction conditions, high ipso-selectivity, and good functional group tolerance. A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized.
