Abstract
The title amino-alcohol 4 is an intermediate for the preparation of ch iral bicyclic amidines and guanidines, and also for polyamines with po tential as ligands in enantioselective catalysis. It has been synthesi zed from (S)-methionine 1 via (S)-homoserine lactone 2 and amino-diol 3. Hydrogenolysis of the doubly benzylic hydroxyl group in 3 proved no n-trivial, but was eventually achieved through the application of cata lytic transfer methodology to the bis-acetyl derivative 14.
