Abstract
In 1972 we proposed1 structure 3 for flavipucine, an antibiotic from an Aspergillus flavipes strain. Later we reported2 a novel reaction of 6-methyl-4-hydroxy-2-pyridone with α keto aldehydes which provided 1a from isobutylglyoxal and it was stated that we believed 1a would serve as a key intermediate in the total synthesis of flavipucine 3.
