Stereoselective Syntheses of γ,δ-Bifunctionalized Homoallylic Alcohols and Ethers via Chemoselective Allyl Addition to Aldehydes

, 2019
Stereoselective synthesis of γ,δ-bifunctionalized homoallylic alcohols and ethers via chemoselective allylation is reported. Pd-catalyzed 1,2-diboration of allenylsilane provided a novel 1,1,2-trifunctional allylation reagent.

Preparation of Homoallylic Alcohols by Nickel-Catalyzed Cyclizations of Allenyl Aldehydes

, 2016
The direct cyclization of allenyl aldehydes with organozincs in the presence of Ni(COD)2 provides synthetically versatile homoallylic alcohols. Both monosubstituted and 1,3-disubstituted allenes participate in the process, with the latter allowing ...

Preparation of Homoallylic Homopropargylic Alcohols from 2-Vinyloxiranes

, 2016
β,γ-Unsaturated aldehydes generated in situ by treatment of 2-vinyloxiranes with a catalytic amount of Sc(OTf)3 or BF·OEt2 are effectively trapped by B-allenyl-9-BBN to afford homoallylic homopropargylic alcohols in high yield.

ZrCl₄ mediated cross-cyclization between epoxides and homoallylic alcohols: synthesis of 4-chlorotetrahydropyran derivatives

, 2005
Epoxides undergo cross-cyclization with homoallylic alcohols in the presence of zirconium tetrachloride under mild conditions to afford the corresponding tetrahydropyran derivatives in excellent ...

Alkylidenesilacyclopropanes Derived from Allenes: Applications to the Selective Synthesis of Triols and Homoallylic Alcohols

, 2016
Several alkylidenesilacyclopropanes were prepared by silver-mediated silylene transfer to allenes. Oxasilacyclopentanes derived from allenes were prepared with high regio- and diastereoselectivity by a two-step, one-flask silacyclopropanation/carbonyl ...
