When more than one substituent is attached to a benzene ring, the substituents are numbered so as to give the lowest numbers possible to the substituents. In derivatives with accepted trivial names (such as styrene) the carbon including the functional group inherent to the derivative is assigned ...
A two-step sequence consisting of a Sonogashira coupling of polyfluorinated 2-iodoanilines with terminal alkynes, followed by a KOH promoted cyclization of the 2-alkynylanilines thus formed, has been developed as a one-pot synthesis of 2-R-indoles (R=n-Bu, Ph, CH2OTHP→CH2OH, C(CH3)2OH...
