Todd-Lab: Matthew Todd Efficient and chemoselective alkylation of amines/amino acids using alcohols as alkylating reagents under mild conditions - Chemical Communications (RSC Publishing) - http://pubs.rsc.org/en... January 24, 2011 from Bookmarklet - Comment - Like Ahamed liked this 10.1039/C0CC01487G. Pretty. Very selective N-methylation, presumably discovered as a byproduct from a debenzylation reaction. This must be known, but the selectivity is still very nice. - Matthew Todd This is a typical de-benzylation condition and i used many a times, never observed any alkylation. Table-2 entry-9. Proline to N-ethylproline in 85% yield? using 10%Pd/C in EtOH. Not done a reaction with a MeOD. Im not impressed. - Ahamed secondary alcohols oxidized to the corresponding ketone without oxidants under the hydrogenation conditions, see this paper. http://pubs.acs.org/doi... - Ahamed So MeOH ------> HCHO which then forms imine and this imine gets reduced under Pd/C, H2 conditions. The first part is strange. - Ahamed
Kudos to the Fagnou Group

Science and Reason Net Kudos to the Fagnou Group - http://chemicalcrystallinity.b... January 20, 2011 from Research Blogging - All... - Comment - Like I am continuously impressed by the publications that have appeared since Prof. Keith Fagnou's shocking passing a little over a year ago. The chemical community still mourns; it is clear from these post-mortem publications that Fagnou's - and his clearly dedicated and talented graduate students and post-docs - brilliance lives on. The chemistry that Fagnou has truly spearheaded, direct C-H functionalization, is a method of forming C-C, C-N, C-B, etc bonds without having to prepare one of the coupling partners, as in traditional transition-metal catalyzed cross-coupling reactions. Palladium, rhodium and ruthenium are commonly used catalysts in direct C-H functionalization reactions. Fagnou has published a great deal on arylation reactions of a wide variety of substrates and even a bit on direct benzylation reactions. Some fairly recent reviews are linked in a previous post.A recent publication in Journal of Organic Chemistry (doi: 10.1021/jo102081a), "Predictable and Site-Selective... - Charles Daney
