Abstract
The compounds 2-N-methylamino-3-methoxythiophene and 2-N-phenylamino-3 -methoxythiophene obtained in fair to good yields in a novel one-pot s ynthesis from methyl or phenyl isothiocyanate and 1-lithiomethoxyallen e have been shown to be in equilibrium with the imino tautomers. The a nalogous 3-methylthio derivatives obtained by a similar procedure from 1-lithiomethylthioallene exist exclusively in the amino form. (C) 199 8 Elsevier Science Ltd. All rights reserved.
