资源简介:
The bifunctional
N-heterocyclic carbene catalyzed [3 + 4] annulation
of enals and 5-alkenyl thiazolones was developed, giving the corresponding
thiazole-fused ε-lactones in high yields with excellent diastereoselectivties
and enantioselectivities. The thiazole-fused ε-lactone could
be isomerized to the spirocyclic thiazolone–cyclopentanone
without erosion of enantioselectivity.
