8-Oxabicyclo[3.2.1]octan-3-one derivatives serve as excellent models that elucidate factors controlling the reactivities and selectivities in the Baeyer-Villigeroxidation. The regioselectivity of ...
Asymmetric synthesis of seven-carbon segments of the phorboxazoles and (−)-discodermolide: Complementary route from racemic trans-2,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one

The C20–C26 segment of the phorboxazoles A and B and the C1–C7 segment of (−)-discodermolide were synthesized in excellent chemical and optical yield using trans-2,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one rac-1 with four stereogenic centres and three prostereogenic sp2-sites as an early racemic switch.
Asymmetric [4+3] cycloadditions from chiral α-chloro imines

日期:1997.5
The first asymmetric [4+3] cycloadditions of 2-aminoallyl cations derived from chiral a-chloro imines to furan and pyrrole systems are reported. The absolute configuration of the major enantiomer of the bicyclic ketone 4a derived from the cycloadducts has been elucidated, and possible rationales for the observed stereoselectivity are discussed.

Silacupration of oxabicyclic compounds. An interrupted ring opening reaction

Oxabicyclo[3.2.1]octenes have been found to undergo silacupration when treated with (PhMe2Si)Cu.LiCN. Ring closure of the cuprate onto a remote carbonyl group at C-3 provides tricyclic compounds. Trapping experiments with a variety of other electrophiles prior to the closure reaction have also been achieved.
