We have demonstrated that electrophilic substitution of 3-substituted indoles with 2-cyclohexenone will readily occur at the nitrogen. Furthermore, the extent of regioselectivity is dependent on reaction solvent and the C3-substituent. Excellent conversion is obtained with good to excellent isolated yields of N- and C2-adducts. In general, more polar, aprotic solvents (CH3CN) give greater N-selectivity whereas with polar protic solvents (CH3OH) an increase in the C2-adduct is observed. 2010-04-27T05:46:48.392Z ]]>
