Popis: International audience; Tertiary alcohols are widely represented in nature and among bioactive molecules. Their importance is attested by the continuous efforts to meet the challenge of their stereoselective synthesis. In this context, we propose an enzymatic approach, involving class II pyruvate aldolases. These enzymes are shown to catalyze selective cross-aldol reactions between pyruvic acid or derivatives as nucleophiles and a series of ketones as electrophiles. This catalytic activity is exemplified by the highly stereoselective preparation of seven branched ketols with good yields. One of them was readily converted into a constrained 4-hydroxyproline analogue in a multienzymatic one-pot one-step process.
