| 6-氯-3,4-二氢-2H-1-萘酮 | 6-chloro-3,4-dihydronaphthalen-1(2H)-one | 26673-31-4 | C10H9ClO | 180.634 |
A series of guanidine–bisurea bifunctional organocatalysts 4, with chiral centres located outside the urea groups, were synthesized. The novel catalyst 4 is conformationally more flexible than the original catalyst 1. In α-hydroxylation of tetralone- derived β-keto esters, 4 afforded the corresponding alcohols in high yields with moderate enantioselectivity.
