Sulfur ylides 8.* synthesis of 5-methylthio-7,8-dihydro-4,8a-diazfluorene-6,9-dione
摘要:
Intramolecular cyclization of ketostabilized sulfur ylide obtained from beta-alanine and 2.3-pyridinedicarboxylic anhydride was studied. The structure of the reaction product, 5-methylthio-7,8-dihydro-4,8a-diazafluorene-6,9-dione, was established by X-ray diffraction analysis.
