Halogenovinyl Sulfones. 6.<sup>1</sup> Synthesis of Condensed Heterocycles by Diastereoselective Intramolecular Diels−Alder Reactions of Sulfonyl-Substituted Trienes
Sulfonyl trienes having a chiral center on the allyl carbon of the diene moiety were prepared from L-amino acid as chiral building blocks. Intramolecular Diels-Alderreaction of the sulfonyl trienes having E-geometry on the diene moiety proceeded on the si-face and exo-selectively to give cis-isoindoles as a sole product in good yields. But using the sulfonyl trienes having Z-geometry on the diene
