Construction of two vicinal quaternary carbons by asymmetric allylic alkylation: Total synthesis of hyperolactone C and (-)-biyouyanagin A

Call on triple A: Palladium-catalyzed asymmetric allylic alkylation (Pd-AAA; see scheme) has enabled a concise and efficient synthesis of hyperolacto ne C and (-)-biyouyanagin A in only six (20% Overall yield) and seven (8% overall yield) steps, respectively. The enantiomers of these natural products were also prepared by exploiting the same methodology.

2-Diazo-1,5-diaryl-1,3,5-pentanetriones and ethyl 2-diazo-5-aryl-3,5-dioxopentanoates were obtained in the reaction of 5-aryl-2,3-dihydro-2,3-furandiones with aroyldiazomethanes and diazoacetic ester.In some cases the formation of diazopentanetriones is a
