title: The microbial oxygenation of the benzylisoquinoline alkaloid laudanosine.
abstract: The microbial transformation of the benzylisoquinoline alkaloid laudanosine by a strain of Pseudomonas putida gives a metabolite in which O-demethylation of 1 methoxyl group of ring C, and introduction of 1 ketonic oxygen at C9 and 1 phenolic oxygen at ring C have occurred. Also, O-methylcoripalline is formed in this transformation.
