A FACILE ACCESS TO MASKED ISOBENZOFURANS ; HIGH EXO-STEREOSELECTIVITY IN THE DIELS-ALDER REACTIONS OF 4,7-DIHYDRO-4,7-ETHANOISOBENZOFURAN.

The isobenzofuran derivatives precursors 4a-c are readily prepared from 1 ; their Diels-Alder adducts with cis-dienophiles present a stereochemistry endo>exo from 4b,c and, interestingly, only exo (towards the furan moiety) from 4a.
