Jerome J. Graber, MD, MPH Robert Staudinger, MD, FAAN An 82-year-old man presented to us with a 2-year history of progressive difficulty walking. On examination, he had bradykinesia, bradyphrenia, axial rigidity without appendicular rigidity, cogwheeling, or tremor, and restriction of upward and downward gaze. Imaging revealed prominent midbrain atrophy without pontine atrophy, referred to as t...
Anarta Ochsenheimer, 1816 is a hadenine genus restricted to Palaearctic and Nearctic Regions. The genus includes about 80 described species and subdivided into seven subgenera (Hacker 1998; Fibiger et al. 2011): Trichoclea Grote, 1883 (= Hadula Staudinger, 1889), Cardiestra Boursin, 1963, Ptochicestra Hacker, 1998, Aglossestra Hampson, 1905, Calocestra Beck, 1991, Pulchrohadula Hacker, 1998 and...
This study details a modular and general synthesis of a new class of molecules consisting of cruciform pi-systems. The key to synthesizing these molecules was an unprecedented double Staudinger cyclization. Once formed, these rigid compounds assemble into ordered monolayer films on metal and metal oxide surfaces to orient their conjugated, bis-phenyloxazole subunits upright. This surface orient...

[figure: see text] The Staudinger ligation can be used to couple a peptide with a C-terminal phosphinothioester to another with an N-terminal alpha-azido group to form a single peptide that contains no residual atoms. Here diphenylphosphinomethanethiol thioesters are shown to give high isolated yields for this transformation. This finding provides precedent for a powerful and versatile new meth...
