Synthesis of the complex bridged 1,5-oxazabicycles via one-pot reactions of 4,5-diazafluoren-9-one, alkyl halides, and cyclic 1,3-diketone
摘要:
An efficient and practical procedure for the preparation of the complex bridged 1,5-oxazabicycles was developed via a one-pot domino reaction of 4,5-diazafluoren-9-one, reactive alkyl halides, and cyclic 1,3-dicarbonyl compounds.
