Abstract

1502527 Cyclopropane derivatives ROUSSEL UCLAF 6 April 1976 [7 April 1975] 13941/76 Heading C2C The invention comprises a process for the preparation of compounds of the formula where R is C 1- C 6 alkyl, each R 1 is C 1 -C 4 alkyl or the two R 1 radicals together represent -(CH 2 ) n - in which n is 2 or 3 and X is O or S by reacting a compound of the formula in the presence of a strong base with a triphenyl isopropyl phosphonium halide. The invention further comprises methyl 2,2-dimethyl-3RS- formyl - cyclopropane - 1RS - carboxylate diethyl acetal and methyl 2,2-dimethyl-3RS- formyl-cyclopropane-1RS-carboxylate diethylene acetal. Compounds of Formula III may be hydrolysed under acidic conditions to yield a compound of the formula which may subsequently be saponified to yield the free acid. [GB1502527A]
