A Representative Synthetic Route for C5 Angucycline Glycosides: Studies Directed toward the Total Synthesis of Mayamycin

This study discloses an efficient synthetic route for the regiospecific construction of a C5 glycoside angucycline representative of mayamycin. The key steps are intramolecular aldol condensation and Hauser annulation, and the key precursor for the aldol reaction is accessible through utilization of α-lithiation of a vinyl ether.

Oxidation of alkyl benzenes to corresponding carbonyl compounds with 1,4-dichloro-1,4-diazoniabicyclo [2,2,2] octane bis-chloride in water

The 1,4-dichloro-1,4-diazoniabicyclo [2,2,2] octane bis-chloride oxidation of various alkylbenzenes gives the corresponding carbonyl compounds in water as solvent.
