Abstract
AbstractA racemic 1,1′‐spirobitetralin‐8,8′‐diol (SBITOL) was conveniently synthesized from 3‐methoxybenzaldehyde in 26 % yield over 9 steps and resolved via its bis‐(S)‐camphorsulfonates. The corresponding chiral spirobitetraline monophosphoramidite ligands have been prepared and their rhodium complexes were applied in the asymmetric hydrogenation of dehydroamino esters with good to excellent enantioselectivities (up to 99.3 % ee).
