Title:

PRACTICAL METHOD FOR REDUCING AMIDES AND LACTAMS

Document Type and Number:

WIPO Patent Application WO/2010/073974

Kind Code:

A1

Abstract:

Amides or lactams can be reduced respectively into alcohols or amino alcohols in the presence of an 8(VIII) group transition metal complex, a base and hydrogen gas (H2). By appropriately combining an 8(VIII) group transition metal complex, a base, a reaction solvent, the hydrogen gas pressure and the reaction temperature, a highly practical reduction method can be provided. A practical method for reducing amides and lactams which is applicable to a broad scope of substrates because of being usable as a substitute for the existing method with the use of a stoichiometric hydride reducing agent and ensuring the achievement of desired reduction under relatively mild reaction conditions.
