2(3H)-and 2(5H)-furanones. VII. Chirality transfer on the tetronic acid templates

The chirality transfer on the β-tetronic acid templates has been examined via highly diastereoselective alkylation or the Michael reaction at the α-position of the acids. Synthetic utility of this transfer procedure was demonstrated by the formal synthesis of (+)-cassiol and enantiodivergent synthesis of O-methyljoubertiamine.
