Total Synthesis in Print
Over at the Baran group's "Open Flask" blog, there's a post on the number of total synthesis papers that show up in the Journal of the American Chemical Society. I'm reproducing one of the figures below, the percentage of JACS papers with the phrase "total synthesis" in their title.
You can see that the heights of the early 1980s have never been reached again, and that post-2000 there has been a marked drought. As the post notes, JACS seems to have begun publishing many more papers in total around that time (anyone notice this or know anything about it?), and it appears that they certainly didn't fill the new pages with total synthesis. 2013, though, already looks like an outlier, and it's only May.
My own feelings about total synthesis are a matter of record, and have been for some time, if anyone cares. So I'm not that surprised to see the trend in this chart, if trend it is.
But that said, it would be worth running the same analysis on a few other likely journal titles. Has the absolute number of total synthesis papers gone down? Or have they merely migrated (except for the really exceptional ones) to the lower-impact journals? Do fewer papers put the phrase "Total synthesis of. . ." in their titles as compared to years ago? Those are a few of the confounding variables I can think of, and there are probably more. But I think, overall, that the statement "JACS doesn't publish nearly as much total synthesis as it used to" seems to be absolutely correct. Is this a good thing, a bad thing, or some of each?
