General strategy for the syntheses of corynanthe, tacaman, and oxindole alkaloids.
We report herein the total synthesis of the corynanthe alkaloid dihydrocorynantheol and the formal syntheses of the indole alkaloids tacamonine, rhynchophylline, and hirsutine. The strategies forExpand
Concise, stereoselective approach to the spirooxindole ring system of citrinadin A.
The spirooxindole ring system of citrinadin A has been synthesized with excellent control over the absolute stereochemistry at the spirocenter. The key step involves a novel diastereoselectiveExpand
Enantioselective Total Syntheses of Citrinadins A and B. Stereochemical Revision of Their Assigned Structures
The concise, enantioselective total syntheses of (−)-citrinadin A and (+)-citrinadin B in a total of only 20 and 21 steps, respectively, from commercially available starting materials are described.Expand
Enantioselective Total Syntheses of Citrinadins A and B. Stereochemical Revision of Their Assigned Structures.
Starting from commercially available materials the enantioselective 20 and 21 step syntheses of (-)-citrinadin A and (+)-citrinadin B result in revison of the structures of the natural materials toExpand
