An Alternative Synthesis of Bisnoraldehyde, an Intermediate to Progesterone and Corticosteroids

New pathway to bisnoraldehyde (BNA) from waste soya bean residues. The original route to BNA uses heavy metal catalysts that generate toxic waste, which is harmful to human health and the environment. This novel route to BNA from soya bean residues uses bleach and a catalyst cofactor system. This new process generates a nontoxic, aqueous waste stream and recoverable organic solvents that can be reused. The process also avoids toxic reagents.
