(2S)-2-(3-Oxo-1,4-dioxaspiro­[4.5]decan-2-yl)ethanoic acid

Abstract

The title compound, C10H14O5, is an inter­mediate in our study of the asymmetric synthesis of α-hydroxy­alkanoic acids. The structure consists of 1,4-dioxaspiro[4,5]decane skeleton formed when the cyclohexylidene group binds to both of the hydroxyl groups of carboxylic groups of the starting malic acid. The six-membered ring adopts a chair conformation
