Short Syntheses of 4‐Deoxycarbazomycin B,Sorazolon E,and (+)‐Sorazolon E2

Short syntheses of 4‐deoxycarbazomycin B and sorazolon E were established through the condensation of cyclohexanone and commercially available 4‐methoxy‐2,3‐dimethylaniline, followed by Pd^II‐catalyzed dehydrogenative aromatization/intramolecular C−C bond coupling and deprotection. A chiral dinuclear vanadium complex (R _a,S,S )‐ 6 mediated the enantioselective oxidative coupling of sorazolon E, affording (+)‐sorazolon E2 in good enantioselectivity.
