Synthese von 4,4-Bis(trifluormethyl)-1-oxabuta-1,3-dienen
摘要:
Silyl enol ethers (1) and hexafluoroacetone (2) react to give O-silylated aldol adducts 3 which, after desilylation with methanol/hydrochloric acid, are transformed into 4.4-bis(trifluoromethyl)-1-oxabuta-1,3-dienes (5) on treatment with trifluoroacetic acid anhydride/pyridine.
