| 5,8-二甲氧基-1-四氢萘酮 | 5,8-dimethoxytetralone | 1015-55-0 | C12H14O3 | 206.241 |
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.
