The epoxidation reactions of a series of cis-3,4-disubstituted-(CH2X)-cyclobutenes with dimethyldioxirane (DMD) and mClPBA have been investigated with both reagents. A remarkable syn diastereoselectivity in the formation of the epoxide has been obsd. for substrates bearing electron withdrawing substituents.

Abstract
The epoxidation reactions of a series of cis-3,4-disubstituted-(CH2X)-cyclobutenes with dimethyldioxirane (DMD) and mClPBA have been investigated with both reagents. A remarkable syn diastereoselectivity in the formation of the epoxide has been obsd. for substrates bearing electron withdrawing substituents.File in questo prodotto:
