obtained in one preparative stage from α-lithiated methoxyallene and 2-methoxyethyl isothiocyanate, a facilecleavage of a C–O bond in the N-(2-methoxyethyl) substituent by the t-BuOK–DMSO system has been discovered, opening access to a new class of N-vinylpyrroles (through β-elimination of methanol).
