Simple and facile synthesis of tetralone-spiro-glutarimides and spiro-bisglutarimides from Baylis–Hillman acetates†
Abstract
A simple and convenient synthesis of di(E)-arylidene-tetralone-spiro-glutarimides from Baylis–Hillman acetates via an interesting biscyclization strategy involving facile C–C and C–N bond formation is described. Also, one-pot multistep transformation of the Baylis–Hillman acetates into di(E)-arylidene-spiro-bisglutarimides is presented.
