Abstract
Tricyclic adducts (6a-c) were isolated as mixtures of dktereoisorners which could be distinguished on t. 1. c. and in their 300 MI-ix pmr spectra. So far, however, all attempts to separate the diastereoisomers by hp 1. c. have resulted in decomposition of the cycloadducts. A single-crystal X-ray structure determination on the (ethylthio)-cycloadduct (5a) has confirmed its structure and the expected regiochemisuy of the cycloaddition. The ...
