A convenient and general method for the regiospecific synthesis of three novel series of 1-(2-thenoyl)-, 1-(2furoyl)-and 1-(isonicotinoyl)-3-alkyl(aryl)-5-hydroxy-5-trifluoromethyl-4,5-dihydro-1H-pyrazoles, in good yields (53 -91 %), from the cyclocondensation reactions of 1,1,1-trifluoro-4-alkoxy-4
Claisen rearrangement of ally1 vinyl ethers is an important general method of carboncarbon bond formation for synthesis of y,b-unsaturated aldehydes and ketones. 1 Syntheses of y,b-unsaturated esters and amides are similarly achieved by rearrangements of 2-alkoxy and 2amino-3-oxa-1,5-hexadienes.
