First asymmetric total synthesis of Us-7 and -8, novel D-seco Corynanthe-type oxindole alkaloids from uncaria attenuata: Structure revision of Us-7 and determination of absolute stereochemistry

(Matrix presented) Starting from (S)-glycidol, the asymmetric total synthesis of novel D-seco Corynanthe-type oxindoles Us-7 and Us-8 was accomplished. The structure of Us-7 was revised from the reported structure 1 with the (3R,7S) form to structure 22 w
