approach for the regioselectivesynthesis of 3-O-acyl monoester lutein derivatives (β-ionone selectivity, up to 17:1), using a lipase (Novozyme 435, immobilized CALB), and vinyl carboxylates (vinyl propionate and stearate) as acyl donors. The regioselectivity arises from the highly stereoselective feature of CALB. This methodology addresses the long-standing problem of regioselective monoesterification
