High trans-2-Decalones by Photoredox Catalyzed β-Isomerization

The synergistic combination of three catalytic processes – photoredox, enamine and hydrogen atom transfer (HAT) catalysis – enabled the β-isomerization of 2-decalones towards the thermodynamically most stable trans-isomers. A library of iridium (III) complexes and organic dyes were screened in combination with cyclic amines and thiols which after optimization gave the desired trans-2-decalones with high trans/cis ratios of 60 : 40 up to 98 : 2.

[4 + 3] cycloadditions of cyclic oxyallyls and cyclic 1,3-dienes

The [4 + 3] cycloaddition of the oxyallyl intermediates, derived from 2-chlorocyclohexanone and related compounds, to cyclic 1,3-dienes under the F?hlisch conditions (Et3N in CF3CH2OH) has been examined to assess its scope

A CONVENIENT PROCEDURE FOR DISSOLVING METAL REDUCTIONS

Alicyclic α,β-unsaturated ketones react with lithium in ethylenediamine, followed by Jones oxidation, to give cyclic ketones in good yield.The stereoselectivity at the β position parallels that observed with lithium in liquid ammonia.
