Titanium mediated olefination of aldehydes with α-haloacetates: an exceptionally stereoselective and general approach to (Z)-α-haloacrylates.
نویسندگان
چکیده
An exceptionally stereoselective and general synthesis of (Z)-α-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from α-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol condensation. Besides being an expedient synthetic procedure, the ready availability of diverse α-haloacetates, exceptional stereoselectivity, and high yields make the process a versatile transformation in organic synthesis. The potential of this method in up-scaling operations has been illustrated.

Organocatalytic stereoselective synthesis of passifloricin A.
The enantioselective synthesis of passifloricin A has been achieved in high diastereomeric excess. The 1,3-polyol moiety was constructed by iterative proline-catalyzed sequential α-aminoxylation and Horner-Wadsworth-Emmons (HWE) olefination of aldehydes while the synthesis of lactone moiety was achieved by ring-closing metathesis (RCM).
متن کاملThe stereoselective synthesis of α-amino aldols starting from terminal alkynes.
A new procedure for the stereoselective synthesis of syn α-amino β-oxy ketones is reported. It consists of two steps; in the first step, α-amino silyl enol ethers having a (Z) geometry are prepared from 1-alkynes via 1-sulfonyl-1,2,3-triazoles. In the second step, the silyl enol ethers undergo the TiCl4-mediated Mukaiyama aldol reaction with aldehydes to produce α-amino β-oxy ketones with excel...
متن کاملHighly selective allylborations of aldehydes using α,α-disubstituted allylic pinacol boronic esters.
α,α-Disubstituted allylic pinacol boronic esters undergo highly selective allylborations of aldehydes to give tetrasubstituted homoallylic alcohols with exceptional levels of anti-Z-selectivity (>20:1). The scope of the reaction includes both acyclic and cyclic allylic boronic esters which lead to acyclic and exocyclic tetrasubstituted homoallylic alcohols. The use of β-borylated allylic boroni...
متن کاملMyoglobin-Catalyzed Olefination of Aldehydes.
The olefination of aldehydes constitutes a most valuable and widely adopted strategy for constructing carbon-carbon double bonds in organic chemistry. While various synthetic methods have been made available for this purpose, no biocatalysts are known to mediate this transformation. Reported herein is that engineered myoglobin variants can catalyze the olefination of aldehydes in the presence o...
متن کاملDiastereoselective oxidative α-amination of aliphatic aldehydes catalyzed by iodine: synthesis of syn-γ-hydroxy-α-amino acetals.
Aldehydes can react with secondary amines to give α-amino acetals via the α-amination of aliphatic aldehydes catalyzed by iodine. The presence of an asymmetric hydroxylated center at the γ-position of the aldehyde was found to induce the stereoselective amino group. This method represents a stereoselective α-amination of γ-hydroxyaldehydes for the synthesis of syn-γ-hydroxy-α-amino acetals in g...
