Abstract
Abstract Reaction of lithiated propargylic amines with isothiocyanates, followed by addition of t -BuOK, t -BuOH and methyl iodide gives either 2,5-bis( N,N -dialkylamino)thiophenes or 1-alkyl-2- N,N -dialkylamino-5-methylthiopyrroles depending on the temperature during the treatment with the base.
