A highly enantioselective enamide hydrogenation route to the title amine was developed. Highlights of the synthesis include an efficient two-step synthesis of a 2-sulfonyl 4-pyridyl ethyl ketone, a simple enamide synthesis by direct condensation of propionamide with a ketone, catalytic asymmetric enamide hydrogenation employing the in-house-developed ligand MeO-BIBOP, and a mild epimerization-free deprotection of a propionamide using Koenig's procedure.

(Chemical Equation Presented) Two practical, efficient, and scalable asymmetric routes to DE ring fragment 7, a key building block in the synthesis of the homocamptothecin derivative diflomotecan 4, are described. The "acetal route" starts from 2-chloro-4
