NEW CHEMISTRY JOURNALS EMERGE PUBLICATIONS: Nature Chemistryy ACS Nano, and ChemSusChem are unveiled

Covers of two of the three announced journals.

HEMISTRY PUBLISHING is flourishing, as evidenced by the proliferation ofjournals dedicated to the topic. The American Chemical Society last week published the inaugural issue of ACS Nano. Paul S. Weiss, distinguished professor of chemistry and physics at Pennsylvania State University, is editor-in-chief of the interdisciplinary monthly journal. ACS Nano includes comprehensive peer-reviewed articles and reviews, as well as perspectives and conversations with leaders in nanoscience and nanotechnology. Wiley-VCH and the Italian and German chemical societies will begin publishing ChemSusChem early next year. The monthly journal will focus on research at the interface of chemistry and sustainability science. Peter Golitz, editor-in-chief of Wiley-

VCH's Angewandte Chemie, will helm the new journal. Nature Publishing Group (NPG) plans to launch Nature Chemistry in the first quarter of 2009, says Philip Campbell, editor-in-chief of Nature. The new monthly journal will publish research, review, and perspective articles; highlights of the latest research; and News and Views, which are analyses examining the wider implications of research, he adds. In its announcement about Nature Chemistry, NPG said the publication "marks a significant new expansion into chemistry publishing." Librarians have sometimes criticized the publisher for launching many journals. But Campbell says: "We have repeatedly found that scientists welcome the arrival of a Nature journal in their discipline, given our track record for leading the citation rankings and also achieving a strong profile beyond the ranks of researchers. Demand for our publications from libraries is also strong. We have enough enthusiastic feedback already to expect that Nature Chemistry'will be a popular journal." Brian D. Crawford, president of the ACS Publications Division, notes that "every competitor in the scientific publishing marketplace introduces innovations that challenge other publishers to improve their products." But he adds that "there are already several highquality journals that feature innovative and impactful chemistry research. So Nature's rationale in launching another general chemistry title is not yet clear, apart from their commercial interests."—SOPHIE ROVNER

istry professor at England's Cambridge University. "It has forced us to be inventive." Of the many hurdles the researchers had to overcome, Ley reckons the most challenging was coupling the molecule's two main fragments. After years of ORGANIC SYNTHESIS: After more than attempts at this convergent approach, the group was two decades, chemists succeed at finally able to marry these two fragments by means of a propargylic enol ether Claisen reaction. The next step, making complex natural product a radical-induced cyclization, elegantly constructed one sterically dense portion of the molecule. "Making a molecule such as this is not an EverestT TOOK 22 YEARS and the efforts of more than climbing exercise; it's about what you learn from the 40 chemists, but Steven V.
