1-Trimethylsilyl 2-methyl 1-propene and 1-trimethylsilyl 3-methyl 1-butene are useful intermediates for the synthesis of furan natural compounds such as Naginata ketone and isoegomaketone.
It was found that 3-(phenylthio)propanal dimethyl acetal is a very useful starting material for the preparation of 3-acylfuranoterpenes. Syntheses of two naturally-occurring furans, isoegomaketone and ipomeanine were described.
