Oxidative Carbon−Carbon Bond Formation in the Synthesis of Bioactive Spiro β-Lactams
摘要:
New oxidative dearomatization procedures leading to Spiro beta-lactams and oxindoles were developed. By a variation of the oxidative reaction conditions, the usefulness of phenolic amides, derived from 4-aminophenol, in the synthesis of structurally different types of molecules was demonstrated.
New synthetic strategies leading to highly functional erythrina, oxindole and pyrrolidinoindoline skeletons have been developed and an efficient formal syntheses of (+/-)-demethoxyerythratidinone reported.
