Asymetric Diels-Alder Reactions with γ-Functionalized α,β-Unsaturated Chiral N-Acyloxazolidinones: Synthesis of (+)-S-145

Martinelli, Michael J.

, p. 5065 - 5073 (2007/10/02)

An extension of the asymmetric Diels-Alder cycloaddition with chiral γ-substituted, α,β-unsaturated imides is described.The application of these results to the synthesis of the potent TxA2 receptor antagonist (+)-S-145 was successfully achieved in a practical manner.
