Title: A C=O⋅⋅⋅Isothiouronium Interaction Dictates Enantiodiscrimination in Acylative Kinetic Resolutions of Tertiary Heterocyclic Alcohols
Abstract

A combination of experimental and computational studies have identified a C=O⋅⋅⋅isothiouronium interaction as key to efficient enantiodiscrimination in the kinetic resolution of tertiary heterocyclic alcohols bearing up to three potential recognition motifs at the stereogenic tertiary carbinol center. This discrimination was exploited in the isothiourea‐catalyzed acylative kinetic resolution of tertiary heterocyclic alcohols (38 examples,s factors up to >200). The reaction proceeds at low catalyst loadings (generally 1 mol %) with either isobutyric or acetic anhydride as the acylating agent under mild conditions.

  2. Abstract

    The full scope and limitations of the catalytic acylative kinetic resolution of a range of tertiary heterocyclic alcohols (78 examples,sup to >200) is reported under operationally‐simple conditions, using low loadings of a commercially available Lewis basic isothiourea catalyst, HyperBTM (generally 1 mol %). The protocol is highly effective for the kinetic resolution of 3‐substituted 3‐hydroxyoxindole and α‐substituted α‐hydroxylactam derivatives bearing up to three potential recognition motifs at the stereogenic tertiary carbinol center. The full power of this methodology has been showcased through the synthesis of highly enantioenriched biologically‐active target compounds in both enantiomeric forms. To provide further insight into the reaction mechanism, a detailed kinetic analysis of this Lewis base‐catalyzed acylation of tertiary alcohols is reported using the variable time normalization analysis (VTNA) method.

  4. Abstract

    Herein, we present an approach for catalytic orthogonal glycosylation utilizing earth‐abundant copper carbenes. This method operates under mild conditions and employs readily accessible starting materials, including benchtop stable enynal‐derived glycosyl donors, synthesized at the gram scale. The reaction accommodates a variety of glycosyl acceptors, including primary, secondary, and tertiary alcohols. The enynal‐derived copper carbenes exhibit remarkable reactivity and selectivity, allowing for the formation of glycosidic linkages with different protecting groups and stereochemical patterns. This approach provides access to both 1,2‐cis‐ and ‐trans‐glycosidic linkages. The product stereoselectivity is independent of the anomeric configuration of the glycosyl donor, which also has orthogonal reactivity to widely used alkynes and thioglycoside donors. An iterative synthesis of a trisaccharide further demonstrates the application of this orthogonal reactivity.

  5. Abstract

    The direct formation of aryl C−O bonds via the intramolecular dehydrogenative coupling of a C−H bond and a pendant alcohol represents a powerful synthetic transformation. Herein, we report a method for intramolecular arene C−H etherification via an umpoled alcohol cyclization mediated by an I(III)N‐HVI reagent. This approach provides access to functionalized chromane scaffolds from primary, secondary and tertiary alcohols via a cascade cyclization‐iodonium salt formation, the latter providing a versatile functional handle for downstream derivatization. Computational studies support initial formation of an umpoled O‐intermediate via I(III) ligand exchange, followed by competitive direct and spirocyclization/1,2‐shift pathways.
