(Matrix presented) A unified strategy for the divergent and stereocontrolled introduction of the (E)- and (Z)-enamide side-chains of oximidines I, II, and III, salicylihalamides A and B, lobatamides A and D, and CJ-12,950 is detailed. The synthesis relied on the copper-promoted C-N coupling of (E)-and (Z)-vinyl iodides with a protected maleimide hemiaminal followed by deprotection and reaction of the resulting (E)- or (Z)-enelactam hemiaminals with O-methylhydroxylamine or propylidenetriphenylphosphorane.

NaBH4 reduction of citraconimide derivatives regioselectively afforded 5-hydroxy-4-methyl-1,5-dihydropyrrol-2-ones, whereas NaBH4-CeCl3 or DIBAL-H reduction gave 5-hydroxy-3-methyl-1,5-dihydropyrrol-2-ones.
