| 3,4-二氢-6-(苯基甲氧基)-1(2H)-萘酮 | 6-benzyloxy-3,4-dihydro-2H-naphthalen-1-one | 32263-70-0 | C17H16O2 | 252.313 |
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.
