A snapshot of the chemical blogosphere

I want to show the mathematicians the vibrancy and value of the chemical blogosphere so – at random – I picked today’s TotallySynthetic. By chance it’s very fitting as it is a review of a paper by one of the blogospheric heroes – Tenderbutton (== Dylan Stiles). Dylan wrote a fascinating and idiosyncratic blog for over a year until his supervisor and pressure of work combined to stop him – fittingly he has a regular blogging column for a chemical publisher. Here’s a flavour of the current post which I’ll show tomorrow:

Spirotryprostatin B

27 June 2007 spirotryprostatin.jpg
Trost, and Stiles. Org. Lett., 2007, ASAP. DOI: 10.1021/ol070971k.
He’s done it :) . Those of us who read Tenderbutton from the start will have known of Dylan’s work on this tasty little number, and he’s done it proud. Eight steps to the natural product; we’ll start with step one (or rather, the first non-literature step):
We’ve looked at Otera’s catalyst before, but as a quick reminder, it’s a funky trans-esterification catalyst. It’s been known for a little while, and the mechanism is in this JOC article. Nice to see it being used; what was it like to handle, Stiles?
Good job, old chap!

    June 28th, 2007 at 1:56 A lovely detail is that a simple oxindole was used as a starting material…

    June 28th, 2007 at 2:32 Could someone (maybe even Dylan) comment … Why can’t you use any of the plethora of other esterification catalysts? Thanks.

    June 28th, 2007 at 2:32 just a doubt…how is otera’s catalyst superior to the usual transesterification catalyst , titanium isopropoxide?

    June 28th, 2007 at 2:37 #1Absolutely. This guy, Trost, is plagiarizing Baran!

    June 28th, 2007 at 3:31 #2This is the one-million-dollar question!Provocateur’s comment about the “usual transesterification catalyst” makes me laugh. There are probably as many usual transesterification catalysts as there are Synth. Commun., Tet. Lett., Chem. Commun. or Org. Lett. articles titled “XYZ, a superactive catalyst for (trans)esterification of QWERTY-acids with YTREWQ-alcohols under mild conditions”.
    PPS: I have read Otero’s book on esterification : http://www.wiley.com/WileyCDA/WileyTitle/productCd-3527304908.html
    This is the poorest book I read from Wiley. After reading this book and many more articles on the topic I came to the conclusion that this field is a hoax.

    Link rot – the JOC ref doesn’t render in Mozilla and it’s closed source. Who’s your audience? Some snotty clique who have access to an athens account? Expected better, Dr M-R.

    (1) Although I can justifiably be accused of linkrot in many of my works, this isn’t one. The body of the message was lifted directly from TotallySynthetic (which being CC is fine). I have no particular desire to encourage people to read papers on synthetic organic chemistry which is as much sport as science. [1]
    What I (or WordPress) have failed to do is show which the quotations are. Normally I indent it, but that’s tricky and rendering in italics can destroy the whole of Planet BlueObelisk. I will amend the post to show the quotation.
    [1] This is a case in point. The compound was reported 11-12 years ago since which there have been several syntheses but no further papers on its biology. From which I conclude that either the chemists cannot make enough for the biologists or, far more likely, that the biologists aren’t interested in Spirotryprostatin B.
