ACYCLIC STEREOCONTROL BY HETEROCONJUGATE ADDITION--4 ANTI-DIASTEREOSELECTION BY A β-CHELATION EFFECT

High selectivity in heteroconjugate addition for C-C bond formation with complete syn-diastereoselection has been attributed to the chelation effect between the α-oxygen atom of the substrate and the nucleophile anions through metal cations.Herein is desc

Synthetic studies toward marine toxic polyethers. 4. Synthesis of segment-A of okadaic acid via anti-selectivity by heteroconjugate addition

Segment-A of okadaic acid was synthesized in an optically active form by coupling the lithium acetylide (segment-A2) and the previously prepared segment-A1. The key step was the preparation of the anti-diastereoisomer for the C-12/13
