With 1,4-diketones the distribution of the reduction products is dependent on the stereochemical situation of the two carbonyl functions.10 In acyclic derivatives, with no stereochemical interaction between the two carbonyl functions, the ketone groups are independently reduced to give methylene products...

One of the areas we have decided to work on is to create 2 cyclohexene-1-ol from 2-cyclohexene-1-one, so we can create varied complex structures. You may ask why we don't just buy it, well it will cost us £77 for just 5 grams of material which is no where near enough for ...

The protocol involves methylation of the dienolate, reduction of the alkene, the Grignard reaction of the carbonyl group, a Wittig reaction, hydroboration with BH3, the oxidation and bromination with a 49% overall yield. For the methylation and reduction steps, the effects o...

CBSketonereduction, which uses aboranereagent as a reductant, is part of many processes. The catalysts for this reaction are boron-containing derivatives ofamino alcohol, and BH3-THF and BH3-dimethylsulfide (BH3-DMS) are common reducing agents. Although this is certainly a reliable reaction, ...
