Dual Activation of Unsaturated Amides with Schwartz's Reagent: A Diastereoselective Access to Cyclopentanols and N,O-Dimethylcyclopentylhydroxylamines.

The diastereoselective access to cyclopentanols and N,O-dimethylcyclopentylhydroxylamines from 4-pentenoic acid-derived Weinreb amides is described. Based on the concomitant generation of both the nucleophilic and the electrophilic poles by hydrozirconati

Highly enantioselective organocatalytic oxidative kinetic resolution of secondary alcohols using chiral alkoxyamines as precatalysts: Catalyst structure, active species, and substrate scope

The development and characterization of enantioselective organocatalytic oxidative kinetic resolution (OKR) of racemic secondary alcohols using chiral alkoxyamines as precatalysts are described. A number of chiral alkoxyamines have been synthesized, and their structure-enantioselectivity correlation study in OKR has led us to identify a promising precatalyst, namely, 7-benzyl-3-n-butyl-4-oxa-5-azahomoadamantane, which affords various chiral aliphatic secondary alcohols (ee up to >99%, krel up to 296). In a mechanistic study, chlorine-containing oxoammonium species were identified as the active species generated in situ from the alkoxyamine precatalyst, and it was revealed that the chlorine atom is crucial for high reactivity and enantioselectivity. The present OKR is the first successful example applicable to various unactivated aliphatic secondary alcohols, including heterocyclic alcohols with high enantioselectivity, the synthetic application of which is demonstrated by the synthesis of a bioactive compound.

Highly enantioselective organocatalytic oxidative kinetic resolution of secondary alcohols using chirally Modified AZADOs

A highly enantioselective organocatalytic oxidative kinetic resolution (OKR) of racemic secondary alcohols has been accomplished using asymmetric organocatalysis. A panel of chirally modified 2-azaadamantane N-oxyls (AZADOs) exhibit superior catalytic act

Asymmetric hydrogenation of 2-arylated cycloalkanones through dynamic kinetic resolution

Asymmetric hydrogenation of 2-arylcycloalkanones with trans-RuCl 2(binap)(1,2-diamine) and t-C4H9OK in 2-propanol selectively gives the corresponding cis-2-arylcycloalkanols in excellent enantiomeric purity and high yield.

Kinetic resolution of (±)-trans- and (±)-cis-2- phenylcyclopentanamine by CALB-catalyzed aminolysis of esters: The key role of the leaving group

Kinetic resolution of (±)-trans- and (±)-cis-2- phenylcyclopentanamine is effectively performed by lipase B from Candida antarctica, (CALB)-catalyzed aminolysis reaction. Whereas reaction between (±)-trans-2-phenylcyclopentanamine and ethyl acetate proceeds with a very high E value (>200) and conversion (50%), the corresponding acetylation of (±)-cis-2-phenylcyclopentanamine happens with low E value (16) and conversion (28%). Nevertheless, this problem is overcome using other acyl donors such as (±)-1-phenylethyl and (±)-cis-2-phenylcyclopentyl methoxyacetates. The influence of the acyl donor on the CALB-catalyzed aminolysis of (±)-cis-2-phenylcyclopentanamine is also studied.
