Abstract

Procedure for the production of cyclopropane derivatives, of formula I: ** (See formula) ** where D is one of the four carbocycles of formulas IIa, IIb, IIc or IId, ** (See formula) ** R1 is hydrogen or alkyl of 1 to 8 carbon atoms, cycloalkyl of 3 to 10 carbon atoms or aralkyl of 7 to 12 carbon atoms, and R2 and R3 are, independently, hydrogen or alkyl of 1 to 4 carbon atoms; characterized in that any protecting group present in a compound of formula III is removed, ** (See formula) ** wherein R1, R2 and R3 have the meanings indicated above, R4 is trialkylsilyl or tetrahydropyranyl, and A is a carbocycle of formula IIa or IIb, defined above, or of formula IIe or IIf: ** (See formula) ** by hydrolysis in an acidic medium, preferably at a slightly elevated temperature.
