✦ Synopsis


Several synthons of b-carboxy carbanions (2) have been added to aldehydes and/or ketones the products ultimately converted into y-butyrolactones Q).l However, this methodology normally requires the use of system. We wish to report a B-lithiopropionate (2) to an adduct. complex reagents and/or several steps to elaborate the butanolide direct synthesis of y-lactones which involves the addition of lithium aldehyde or ketone followed by lactonization of the y-hydroxy acid --COH 2
