Enantioselective alpha-functionalizations of ketones via allylic substitution of silyl enol ethers

The enantioselective construction of carbon?heteroatom and carbon?carbon bonds that are alpha to ketones leads to the formation of substructures that are ubiquitous in natural products, pharmaceuticals and agrochemicals. Traditional methods to form such bonds have relied on combining ketone enolates with electrophiles. Reactions with heteroatom-based electrophiles require special reagents in which the heteroatom, which is typically nucleophilic, has been rendered electrophilic by changes to the oxidation state. The resulting products usually require post-synthetic transformations to unveil the functional group in the final desired products. Moreover, different catalytic systems are typically required for the reaction of different electrophiles. Here, we report a strategy for the formal enantioselective alpha-functionalization of ketones to form products containing a diverse array of substituents at the alpha position with a single catalyst. This strategy involves an unusual reversal of the role of the nucleophile and electrophile to form C?N, C?O, C?S and C?C bonds from a series of masked ketone electrophiles and a wide range of conventional heteroatom and carbon nucleophiles catalysed by a metallacyclic iridium catalyst.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: (S)-(Tetrahydrofuran-2-yl)methanamine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7175-81-7, in my other articles.

Radical cyclizations of acylsilanes in the synthesis of (+)-swainsonine and formal synthesis of (-)-epiquinamide

Radical cyclization of acylsilane is an useful synthetic methodology. To demonstrate the versatility of this method using the cyclization as a key step, polyhydroxylated indolizidine (+)-swainsonine was synthesized through two different bond connection approaches to construct the bicyclic skeleton. In the first approach, we used 2,3-isopropylidene-d-ribono-1,4-lactone (20) as a chiral building block to form the indolizidine skeleton through a 1,6-cyclization. In the second approach, (S)-(+)-5-oxo-2-tetrahydrofurancarboxylic acid (23) was used to construct the same ring system through a 1,5-cyclization. Starting from acid 23, we also synthesized exo-1-hydroxyquinolizidin-4-one (56), which was a synthetic intermediate in the synthesis of polyhydroxylated quinolizidine (-)-epiquinamide. 2011 Elsevier Ltd.
