The ring opening of vinyloxiranes with aryl borates under very mild and neutral conditions affords new hydroxyphenols with interesting levels of regio- and stereoselectivity. The subsequent Mitsunobu-type cyclodehydration proceeds with a good yield giving a new and easy access to cycloalkenobenzofurans.

Abstract
The ring opening of vinyloxiranes with aryl borates under very mild and neutral conditions affords new hydroxyphenols with interesting levels of regio- and stereoselectivity. The subsequent Mitsunobu-type cyclodehydration proceeds with a good yield giving a new and easy access to cycloalkenobenzofurans.File in questo prodotto:
