Accessing the structural diversity of pyridone alkaloids: Concise total synthesis of rac-citridone A

A unique route to the structural diversity of pyridone alkaloids is described based on the concept of a common synthetic strategy. Three different core structure analogues corresponding to akanthomycin, septoriamycin A, and citridone A have been prepared by using a highly selective and novel carbocyclization reaction.

Synthesis of (2R,4R)-supellapyrone, the sex pheromone of the brownbanded cockroach, Supella longipalpa, and its three stereoisomers

Supellapyrone [(2R,4R)-5-(2,4-dimethyl)-3-methyl-2H-pyran-2-one (1)], the female sex pheromone of the brownbanded cockroach (Supella longipalpa), and its three stereoisomers were synthesized by employing lipase-catalyzed desymmetrization or enantiomer separation of syn- or anti-2,4-dimethylpentane-1,5-diol (9) as the key step.
