The intramolecular Staudinger-aza-Wittig reaction is used for a general synthesis of 1,2,5,6-tetrahydro-1,2,4-triazines, a structural motif reported for the natural product noelaquinone. The DEF moiety of noelaquinone was obtained in 13 steps and 2% overall yield, and the structure of the synthetic product was confirmed by X-ray analysis.

An efficient asymmetric synthesis of the 22nd amino acid L-pyrrolysine has been accomplished. The key stereogenic centers were installed by an asymmetric conjugate addition reaction. A Staudinger/aza-Wittig cyclization was used to form the acid-sensitive pyrroline ring. Pyrrolysine was synthesized in 13 steps in 20% overall yield.

The development of a lead-mediated α-arylation reaction between aryl azides and β-ketoesters or γ-lactams that facilitates the formation of 3H-indoles is disclosed. Twenty-five examples are included which demonstrate the generality of this reaction to access aryl azides bearing tetrasubstituted o-alkyl substituents. When paired with a Staudinger reduction, this reaction streamlines the synthesi...

Hyponephele Muschamp, 1915 is a Palaearctic genus comprising 39 species (Eckweiler, Bozano, 2011), with most distributed in the Central Asiatic region. During the course of faunistic studies on the butterflies of Tajikistan, a new member of this genus was found; it is described herein as new. It is closely related and sympatric to H. hilaris (Staudinger, 1886) so compared to this one.

Our efforts to develop a scalable and divergent synthesis of cyclic di-nucleotide analog precursors have resulted in (1) an orthogonally protected di-amino carbohydrate as well as (2) the novel application of the Staudinger ligation to provide medium-sized macrocycles featuring carbamate or urea linkages.

A small Central Asian Noctuidae genus Palaeagrotis Hampson, 1907 is revised. One new species, P. adrienneae Volynkin, Gyulai & Behounek, sp. n. is described from South Mongolia. The lectotypes of Hadena inops Lederer, 1853 and Heterographa sibirica Staudinger, 1896 are designated. The adults, and the male and female genitalia are illustrated.

A new species of the Bryophila (Scythobrya) salomonis species-group, B. kaszabi sp. n. is described. A diagnostic comparison is made with B. miltophaea Hampson, 1908 and B. plumbeola Staudinger, 1881. Adults, male and female genitalia of the new and related species are illustrated.
