Enzymatic resolution of dimethyl 2-methylsuccinate, acyloin cyclization and base induced ring contraction provided 1-hydroxycyclopropanecarboxylic acids with high optical purity (>95percent e.e).Their derivatives opened a regio- and stereoselective way to optically active 2-vinylcyclobutanones (>84-90percent e.e), providing useful building blocks for further ring expansions.
