Their precise synthesis is challenging due to the distinct and diverse substitution patterns at the sugar framework, and it is scarcely reported. Orthogonal protection/deprotection strategies for disaccharides are more complex and less developed than those for monosaccharides. We disclose a precise synthesis of PSEs starting from 2,1′:4,6-di-O-diisopropylidene sucrose 7via an orthogonal protection/deprotection and selective cinnamoylation strategy. We demonstrate the strategy for the synthesis of several PSEs cinnamoylated at the O-3 and O-4′ positions of diisopropylidene sucrose 7. The strategy is enabled by a carefully selected and synergistic set of protecting groups and deprotecting agents under the optimized conditions. It potentially gives access to the ∼150 reported PSEs and opens the door for the custom synthesis of unnatural PSEs for industrial applications. The reported work also presents a viable strategy for the general orthogonal protection/deprotection of disaccharides for the precise synthesis of other classes of phenylpropanoid esters and related compounds.||URI:||https://hdl.handle.net/10356/162140||ISSN:||1144-0546||DOI:||10.1039/d2nj00881e||Rights:||© 2022 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
