Dihydropyridone bromide (2) was converted to the corresponding alcohol (1) by reaction with indium in air or with indium followed by treatment with a sulfonyloxaziridine. The alcohol (1) was transformed in four steps to a phenylsulfone‐substituted pipermethystine derivative (10). Reductive cleavage of the phenylsulfone did not yield the pipermethystine natural product. Several new pyridone derivatives
