    Some Natural Product Weirdness

    Let us take a moment to gaze upon the weirdness of natural products. For an organic chemist, these things can at times be startlingly weird, with structures that keep bringing on the “Well, I never would have thought of that” response. I collect especially odd ones as I see them in the current literature, so… Read More

    Predicting – Or Not Predicting – New Materials

    We chemists would love to be able to do just a tiny bit less chemistry now and then and just let models and simulations tell us what would happen instead. Only every once in a while – you wouldn’t want to obtain such a perfectly accurate picture of chemical and physical interactions that there was… Read More

    New Chemistry, Making New Things

    In a perverse way, I’m enjoying how modern organic synthesis is upsetting the classic undergraduate sort of test-question syntheses. You know – Grignards, ester condensations, oxidation and reduction of carbonyls, Wittigs, Sandmeyer reactions, Friedel-Crafts, good ol’ hammer-and-tongs bond formation. I had sophomore organic back i… Read More

    Targeting microRNAs

    Medicinal chemists spend the vast majority of their time targeting proteins. Enzyme active sites, receptors, allosteric sites, interfacial sites – it’s one protein after another, to the point that you can mentally assume that your compounds are going to be hitting the familiar landscape of backbone amide bonds, pi-interacting tryptophan… Read More

    Birch Reduction Without Tears. Or Ammonia. Or Metals.

    The Birch reduction is pretty interesting to run, especially the first time you do it. Liquid ammonia is not a typical reaction solvent, and condensing it off a cold finger always looks a bit like a magic trick. You’ll be standing there with a beaker of sodium or lithium metal pieces (sitting under solvent!), which… Read More

    Odd Peroxides Indeed

    You know, normally when you start combining interesting or reactive functional groups in the same molecule, you end up with something that’s worse than before. Would I pick up a flask containing a compound that has both a perchloryl ester and a geminal di-azide? I would not, and neither should you, should someone ever be… Read More

    The Good Stuff Goes One Way. . .

    I’ve always like the idea of aptamers – as generally used, that word refers to oligonucleotides that are selected for binding to something else (a protein target, for example). You get to use all the tools of molecular biology, which means that you can start out from insanely huge numbers of possible binders and select… Read More

    Defending Drug Synthesis

    This article from Science is a good look at the scientific state of organic synthesis in the pharmaceutical industry. It covers a range of topics which will be familiar to regular readers of this blog as well: synthetic advances such as late-stage functionalization, new bond-forming techniques (photoredox chemistry in particular), the intersection… Read More

    Blue Light Gives Way to Red

    Photochemistry’s rise over the last ten years or so has been one of the big stories in organic chemistry, but there are still some difficulties with using it. The use of photoredox catalysts has brought blue light into a lot of fume hoods, which is certainly more selective and easier to use than than old… Read More

    Leo Paquette, 1934-2019

    So Leo Paquette has died, age 84 – he had been ill for some years (Parkinson’s). Paquette will be well-known to any synthetic organic chemist; his research group at Ohio State had a long record of contributions to the literature. This PDF from the Baran group is an excellent summary of his work, which is… Read More
