A new synthesis of ABT-773 has been reported: The acylation of erythromycin A 9-oxime (I) with acetic anhydride, TEA and DMAP in THF gives the 2',4'',9-tri-O-acetylerythromycin A 9-oxime (II), which is first condensed with 3-(3-quinolinyl)-2-propen-1-ol tert-butyl carbonate (III) by means of Pd2(dba)3 and dppb in toluene and then treated with NaOH to yield 2',4''-di-O-acetyl-6-O-[3-(3-quinolinyl)-2-propenyl]erythromycin A 9-oxime (IV). Reaction of oxime (IV) with NaHSO3 and HOAc in water/THF affords 4''-O-acetyl-6-O-[3-(3-quinolinyl)-2-propenyl]erythromycin A (V), which is benzoylated with benzoic anhydride and TEA in isopropyl acetate/THF to provide 4''-O-acetyl-2'-O-benzoyl-6-O-[3-(3-quinolinyl)-2-propenyl]ery- thromycin A (VI). The reaction of compound (VI) with carbonyldiimidazole (CDI), sodium hexamethyldisilazide (NaHMDS) and ammonia gas in THF/DMF gives the 11-N,12-O-cyclic carbamate erythromycin A derivative (VII). The intermediate 3-(3-quinolinyl)-2-propen-1-ol tert-butyl carbonate (III) has been obtained by Grignard condensation of quinoline-3-carbaldehyde (X) with vinylmagnesium bromide (XI) in THF to give the secondary alcohol (XII), followed by esterification and simultaneous rearrangement with Boc2O in the same solvent.
