Brilliant that FF picks up the graphical abstract! - Egon Willighagen

What we discussed last week. Iron catalysed asymmetric hydrogenation. We can see more papers on this lines..... - Ahamed

Right, so it's transfer hydrog. From the isopropanol. Nice. Like an MPV reduction. - Matthew Todd

Modified Jacobsen's Mn-salen with different linker length and Zn chelation. Changing the linker length changes the porosity and also increases rate and enantioselectivity of epoxidation. Why do they modified Jacobsen's Mn-salen with an additional metal and chelation to get a less effecient catalyst reaction with less stereochemical output? Recyclibility? Who cares..... - Ahamed

Micheal this one is for you....... - Ahamed

Thanks! - Michael Wolfle

This is what we were talking about. Isatin is very inexpensive. Good starting point? - Ahamed

Yes, but ideally you don't want to be isolating aldehydes. It's usually the case that they are derivatised with something else first to make them easy to purify/analyze. The devil's in that detail. We really want a B-H that does not give an aldehyde. - Matthew Todd

Supramolecular catalysis — the assembly of catalyst species by harnessing multiple weak intramolecular interactions — has, until recently, been dominated by enzyme-inspired approaches. Such approaches often attempt to create an enzyme-like 'active site' and have concentrated on reactions similar to those catalysed by enzymes themselves. Here, we discuss the application of supramolecular assembly to the more traditional transition metal catalysis and to small-molecule organocatalysis. The modularity of self-assembled multicomponent catalysts means that a relatively small pool of catalyst components can provide rapid access to a large number of catalysts that can be evaluated for industrially relevant reactions. In addition, we discuss how catalyst–substrate interactions can be tailored to direct substrates along particular reaction paths and selectivities. - Ahamed

Asymmetric Povarov reaction using non-covelent interactions- E.N.Jacobsen way....... - Ahamed

Yes yes yes - Matthew Todd
