ABSTRACT:
The invention relates to a process for the preparation of compounds of the formula I ##STR1## in which n denotes 1, 2 or 3, R denotes acyl, and R.sup.1 denotes alkyl, cycloalkyl, aralkyl or another carboxyl protective group, which comprises radical cyclization of compounds of the formula II ##STR2## in which n, R and R.sup.1 are as defined above, and Hal denotes chlorine, bromine or iodine, to intermediates in this process, and to their use.
