Catalytic strategies towards 1,3-polyol synthesis by enantioselective cascades creating multiple alcohol functions

Abstract

This review highlights the different enantioselective catalyst-controlled cascades creating multiple alcohol functions through the formation of several carbon–carbon bonds. Through subsequent simple derivatization, these strategies ensure the rapid preparation of 1,3-polyols. Thanks to the use of efficient metal- or organo-catalysts, these cascades enable the selective assembly of multiple substrates considerably limiting operations and waste generation. For this purpose, several mono- or bi-directional approaches have been devised allowing successive C–C bond-forming events. The considerable synthetic economies these cascades enable have been demonstrated in the preparation of a wide variety of complex bioactive natural products, notably polyketides.
