Enantiocontrolled Construction of Tricyclic Furan Derivatives via an Asymmetric Diels−Alder Reaction
The two enantiomers of trycyclic furan derivatives were prepared respectively from Diels−Alder reactions of oxycyclic dienes 3a and 3b, followed by degradation of the 2-(benzyloxy)ethyl group. Compounds 3a and 3b can be selectively synthesized by [3+2]-cycloaddition of vinylpropargyltungsten complex...

| Zusammenfassung: | The two enantiomers of trycyclic furan derivatives were prepared respectively from Diels−Alder reactions of oxycyclic dienes 3a and 3b, followed by degradation of the 2-(benzyloxy)ethyl group. Compounds 3a and 3b can be selectively synthesized by [3+2]-cycloaddition of vinylpropargyltungsten complex with (2S)-(benzyloxy)-propanal. |
