Sn/Li exchange reactions in 1,ω-distannylated conjugated trienes and tetraenes: An enabling step for polyene synthesis

Successive treatments of (1E,3E,5E)- or (1E,3Z,5E)-1,6-bis(tributylstannyl) hexa-1,3,5-triene with nBuLi and butanal rendered polyenyl alcohols resulting from one Sn/Li exchange reaction and exhibiting complete retention of the configuration of all C=C bonds. Mono- or dimethylated all-E-configured 1,6-distannylated conjugated trienes as well as all-E-1,8-bis(tributylstannyl) octa-1,3,5,7-tetraene and dimethylated congeners thereof reacted similarly. The respective Sn/Li exchange reactions affected the substructure Bu 3Sn-CH=CH with a 93-94:7-6 preference over Bu3Sn-CMe=CH and with a 90:10 preference over Bu3Sn-CH=CMe. all-E-1-Lithio-6- (tributylstannyl)hexa-1,3,5-triene was incorporated into navenone B after Negishi coupling and into (-)-cicutoxin after acylation. NMR spectroscopy of our navenone B specimen revealed that certain resonances were misassigned previously. Molecular tinkertoy: all-E-1,6-(Tributylstannyl)hexa-1,3,5-triene, all-E-1,8-(tributylstannyl)octa-1,3,5,7-tetraene, and related bis(tributylstannylated) polyenes undergomono-Sn/Li exchange reactions. They set the stage for terminus-differentiating functionalizations, which provide inter alianavenone B and (-)-cicutoxin.

Catalytic α-Deracemization of Ketones Enabled by Photoredox Deprotonation and Enantioselective Protonation

This study reports the catalytic deracemization of ketones bearing stereocenters in the α-position in a single reaction via deprotonation, followed by enantioselective protonation. The principle of microscopic reversibility, which has previously rendered this strategy elusive, is overcome by a photoredox deprotonation through single electron transfer and subsequent hydrogen atom transfer (HAT). Specifically, the irradiation of racemic pyridylketones in the presence of a single photocatalyst and a tertiary amine provides nonracemic carbonyl compounds with up to 97% enantiomeric excess. The photocatalyst harvests the visible light, induces the redox process, and is responsible for the asymmetric induction, while the amine serves as a single electron donor, HAT reagent, and proton source. This conceptually simple light-driven strategy of coupling a photoredox deprotonation with a stereocontrolled protonation, in conjunction with an enrichment process, serves as a blueprint for other deracemizations of ubiquitous carbonyl compounds.

Chemo- and Stereoselective Transition-Metal-Free Amination of Amides with Azides

The synthesis of α-amino carbonyl/carboxyl compounds is a contemporary challenge in organic synthesis. Herein, we present a stereoselective α-amination of amides employing simple azides that proceeds under mild conditions with release of nitrogen gas. The
