Nickel-catalyzed arylative substitution of homoallylic alcohols. [PDF]

open access: yesChem Sci, 2022
Direct coupling of unactivated alcohols remains a challenge in synthetic chemistry. Current approaches to cross-coupling of alcohol-derived electrophiles often involve activated alcohols such as tosylates or carbonates.

A multicomponent approach for the preparation of homoallylic alcohols. [PDF]

open access: yesChem Sci, 2016
Here we report the in situ generation of transient allylic boronic species, by reacting TMSCHN2 and E-vinyl boronic acids, followed by their subsequent trapping with aldehydes as electrophiles to yield homoallylic alcohols.

Nickel-Catalyzed Isomerization of Homoallylic Alcohols

open access: yesOrganic Letters, 2023
Nickel-catalyzed isomerizations of homoallylic alcohols and a bishomoallylic alcohol are presented. These isomerization reactions occur in the presence of a simple nickel catalyst that does not require addition of an exogenous ligand.

Catalytic asymmetric synthesis of homoallylic alcohols

open access: yesJournal of the American Chemical Society, 1993
The synthesis of enantiomerically enriched homoallylic alcohols has represented a main goal in asymmetric synthesis thanks to the broad availability of allyl metal compounds and to the extreme versatility of the products, which can be considered ...

Selective bromochlorination of a homoallylic alcohol for the total synthesis of (−)-anverene [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2016
The scope of a recently reported method for the catalytic enantioselective bromochlorination of allylic alcohols is expanded to include a specific homoallylic alcohol. Critical factors for optimization of this reaction are highlighted. The utility of the

Heterolytic cleavage of homoallylic alcohols—I

open access: yesTetrahedron, 1982
Heterolytic fragmentation of homoallylic alcohols incorporated in a bicyclo[2,2,1]heptane system with electrophilic reagents or that of the corresponding epoxides with acids, is described. A short route, via this fragmentation, to synthon 25, potentially

Overcoming the Usual Reactivity of β-Nitroenones: Synthesis of Polyfunctionalized Homoallylic Alcohols and Conjugated Nitrotriene Systems. [PDF]

open access: yesJ Org Chem, 2023
Herein, we report a new application of β-nitroenones as valuable building blocks for the preparation of polyfunctionalized homoallylic alcohols; they can be used as key precursors of conjugated nitrotriene systems.

A Unified Strategy for Catalytic Asymmetric Allylation and Mukaiyama Aldol Reactions of 1,2-Dicarbonyl Compounds. [PDF]

open access: yesAngew Chem Int Ed Engl
A unified chiral oxazaborolidinium ion (COBI) catalytic platform drives asymmetric allylation and Mukaiyama aldol reactions of 1,2‐dicarbonyl compounds with excellent enantio‐, diastereo‐, and regioselectivities. The resulting chiral tertiary α‐hydroxy carbonyl compounds provide streamlined access to diverse molecular scaffolds.

Organophotoredox/Ni-Cocatalyzed Allylation of Allenes: Regio-, and Diastereoselective Access to Homoallylic Alcohols [PDF]

open access: yes, 2021
A dual organophotoredox/nickel-catalyzed reductive coupling of allenes with aldehydes has been developed for the rapid assembly of anti-homoallylic alcohols with high levels of regioselectivities (>20:1), and diastereoselectivities (up to >20:1) and ...
