2,2-Dimethylcyclopropane-carboxylic acid derivatives

A 2,2-dimethylcyclopropanecarboxylic acid derivative having the formula: STR1 wherein R1 is an alkyl group or an aryl group, R2 is a hydrogen atom, an acyl group, a sulfonyl group or an alkyl group, and each of X1 and X2 is a halogen atom.

EFFICIENT CARBON-CARBON BOND FORMATION WITH THERMALLY STABLE 1,1-DIHALO-2,2,2-TRIFLUOROETHYLZINC REAGENT

The zinc carbenoids CF3CX2ZnX, prepared from CF3CX3 and zinc powder in dimethylformamide, were found thermally stable to add to aldehyde carbonyls in excellent yields.

PRACTICAL AND STEREOCONTROLLED SYNTHESES OF BOTH (1R*,3S*)- AND (1R*,3R*)-3-(2-CHLORO-3,3,3-TRIFLUORO-1-PROPENYL)-2,2-DIMETHYLCYCLOPROPANECARBOXYLATES

The title compounds of (1R*,3S*) configuration were prepared from 3-formyl-2,2-dimethylcyclopropanecarboxylate by addition of CF3CCl2ZnCl, acetylation, and reductive β-elimination with zinc, whereas the (1R*,3R*) isomer was derived from Me2C=CHCH(OH)CCl2CF3 by diazoacetylation, Cu(II) catalyzed intramolecular cyclization, and the zinc reduction.
