Jinxing Ye of the East China University of Science and Technology used (Tetrahedron Lett. 2011, 52, 2715) the Hayashi catalyst to direct the addition of 2 to 1, to give the cyclopropane 3. Jia-Rong Chen and Wen-Jing Xiao of Central China Normal University employed (J. Org. Chem. 2011, 76, 281) a urea catalyst for the addition of 5 to 4. Yasumasa Hamada of Chiba University devised (Tetrahedron Lett. 2011, 52, 987) a different urea catalyst for the addition of 7 to 8, to control both the absolute and relative configuration of 9. Jiyong Hong of Duke University showed (Tetrahedron Lett. 2011, 52, 2468) that the imidazolium-mediated cyclization of 10 proceeded with high diastereoselectivity to give 11. Yixin Lu of the National University of Singapore optimized (J. Am. Chem. Soc. 2011, 133, 1726) a dipeptide-derived phosphine to catalyze the addition of 12 to 13. Karl A. Scheidt of Northwestern University combined (Angew. Chem. Int. Ed. 2011, 50, 1678) a triazolium catalyst with super-stoichiometric Ti(O- i Pr)4 to effect the addition of 15 to 4, to give 16. En route to malyngamide C, Xiao-Ping Cao of Lanzhou University condensed (J. Org. Chem. 2011, 76, 3946) the prochiral commercial monoketal 17 with nitrosobenzene, using proline as a catalyst, to prepare 18. Hong Wang of Miami University showed (Angew. Chem. Int. Ed. 2011, 50, 3484) that a lanthanide-complexed α-amino amide was effective for catalyzing the addition of the prochiral 19 to 4, to give 20. Alexandre Alexakis of the Université de Genève and John C. Stephens of the National University of Ireland, Maynooth, established (Angew. Chem. Int. Ed. 2011, 50, 5095) that the Hayashi catalyst was effective for mediating the addition of 22 to 21, to give the diene 23. Ying-Chun Chen of Sichuan University and Karl Anker Jørgensen of Aarhus University used (J. Am. Chem. Soc. 2011, 133, 5053) the same catalyst for the addition of 24 to 25. The Hayashi catalyst appeared again in the report (Chem. Comm. 2011, 47, 3828) by Magnus Reuping of RWTH Aachen University of the addition of 27 to 28.

Knowledge presented by Oral History (OH) is unique in that it shares the tacit perspective, thoughts, opinions and understanding of the interviewee in its primary form. While teachers, lecturers and other education specialists have at their disposal a wide range of primary, secondary and tertiary sources upon which to relate and share or impart knowledge, OH presents a rich source of information that can improve the learning and knowledge impartation experience. The uniqueness of OH is presented in the following advantages of its use: it allows one to learn about the perspectives of individuals who might not otherwise appear in the historical record; it allows one to compensate for the digital age; one can learn different kinds of information; it provides historical actors with an opportunity to tell their own stories in their own words; and it offers a rich opportunity for human interaction. This article discusses the placement of oral history in the classroom set-up by investigating its use as a source of learning material presented by the National Archives of Zimbabwe to students in the Department of Records and Archives Management at the National University of Science and Technology (NUST). Interviews and a group discussion were used to gather data from an archivist at the National Archives of Zimbabwe, lecturers and students in the Department of Records and Archives Management at NUST, respectively. These groups were approached on the usability, uniqueness and other characteristics that support this type of knowledge about OH in a tertiary learning experience. The findings indicate several qualities that reflect the richness of OH as a teaching source material in a classroom set-up. It further points to weak areas that may be addressed where the source is considered a viable strategy for knowledge sharing and learning. The researchers present a possible model that can be used to champion the use of this rich knowledge source in classroom education at this university and in similar set-ups.

Parapteronemobius contains 7 species or subspecies distributed in East Asia with only one species recorded from China. In this study, we reported the second species, P. chenggong He sp. nov., from Zhejiang. The new species differs from P. dibrachiatus in body size, male genitalia and COI gene. The phylogeny of this genus in subfamily Nemobiinae are discussed based on COI, 18S and 28S genes. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
