Abstract/OtherAbstract:
|
A vinylog of Michael addition (1,6-addition) of azlactones to δ-substituted dienyl N-acylpyrroles has been developed with virtually complete 1,6-, diastereo-, and enantioselectivities by means of chiral P-spiro triaminoiminophosphorane as a catalyst. This system has been successfully extended to an unprecedented bis-vinylog of Michael addition (1,8-addition) of azlactones to ζ-substituted trienyl N-acylpyrroles with high levels of regio- and stereocontrol. |
