Naturally catalytic: The cinchonidine‐ and cinchonine‐derived bifunctional thiourea organocatalysts 1 a and 1 g (see picture) have been applied in the asymmetric hydrophosphonylation of aromatic and heteroaromatic α‐ketoesters for the first time, obtaining S and R products in high yields with good to excellent enantioselectivities (up to 91 % ee).
天然催化:
