The enantioselective bromocyclization of dicarbonyl 1 to form dihydrofuran 3 using thiocarbamate catalyst 2 was developed (Angew. Chem. Int. Ed. 2013, 52, 8597) by Ying-Yeung Yeung at the National University of Singapore. Access to dihydrofuran 5 from the cyclic boronic acid 4 and salicylaldehyde via a morpholine-mediated Petasis borono-Mannich reaction was reported (Org. Lett. 2013, 15, 5944) by Xian-Jin Yang at East China University of Science and Technology and Jun Yang at the Shanghai Institute of Organic Chemistry. Chiral phosphoric acid 7 was shown (Angew. Chem. Int. Ed. 2013, 52, 13593) by Jianwei Sun at the Hong Kong University of Science and Technology to catalyze the enantioselective acetalization of diol 6 to form tetrahydrofuran 8 with high stereoselectivity. Jan Deska at the University of Cologne reported (Org. Lett. 2013, 15, 5998) the conversion of glutarate ether 9 to enantiopure tetrahy­drofuranone 10 by way of an enzymatic desymmetrization/oxonium ylide rearrange­ment sequence. Perali Ramu Sridhar at the University of Hyderabad demonstrated (Org. Lett. 2013, 15, 4474) the ring-contraction of spirocyclopropane tetrahydropyran 11 to produce tetrahydrofuran 12. Michael A. Kerr at the University of Western Ontario reported (Org. Lett. 2013, 15, 4838) that cyclopropane hemimalonate 13 underwent conver­sion to vinylbutanolide 14 in the presence of LiCl and Me₃N•HCl under microwave irradiation. Eric M. Ferreira at Colorado State University developed (J. Am. Chem. Soc. 2013, 135, 17266) the platinum-catalyzed bisheterocyclization of alkyne diol 15 to fur­nish the bisheterocycle 16. Chiral sulfur ylides such as 17, which can be synthesized easily and cheaply, were shown (J. Am. Chem. Soc. 2013, 135, 11951) by Eoghan M. McGarrigle at the University of Bristol and University College Dublin and Varinder K. Aggarwal at the University of Bristol to stereoselectively epoxidize a variety of alde­hydes, as exemplified by 18. The amine 20-catalyzed tandem heteroconjugate addition/Michael reaction of quinol 19 and cinnamaldehyde to produce bicycle 21 with very high ee was reported (Chem. Sci. 2013, 4, 2828) by Jeffrey S. Johnson at the University of North Carolina, Chapel Hill. Quinol ether 22 underwent facile photorearrangement–cycloaddition to 23 under irradiation, as reported (J. Am. Chem. Soc. 2013, 135, 17978) by John A. Porco, Jr. at Boston University and Corey R. J. Stephenson, now at the University of Michigan.

Clemens Krempner of Texas Tech University devised (Chem. Eur. J. 2014, 20, 14959) a very active Al catalyst for the Meerwein-Ponndorf-Verley reduction of a ketone 1 to the alcohol 2. Louis Fensterbank and Cyril Ollivier of UMPC and Jean-Philippe Goddard of the Université de Haute-Alsace showed (Adv. Synth. Catal. 2014, 356, 2756) that visible light could mediate the reduction of the O-thiocarbamate 3 to 4. Soon Hyeok Hong of Seoul National University used (Org. Lett. 2014, 16, 4404) hydrogen from the diol 6 to reduce the nitrile 5, leading directly to the protected amine 7. Alex Adronov of McMaster University (J. Org. Chem. 2014, 79, 7728) and Thibault Cantat of Gif- sur-Yvette (Chem. Commun. 2014, 50, 9349) observed that an aryl amide 8 could be reduced to the amine 9 under conditions that left alkyl amides unchanged. Paul J. Chirik of Princeton University developed (J. Am. Chem. Soc. 2014, 136, 13178) a Co catalyst for the alcohol- directed reduction of a proximal alkene, converting 10 selectively to 11. Yoichiro Kuninobu and Motomu Kanai of the University of Tokyo used (Synlett 2014, 25, 1869) stoichiometric Mo(CO)₆ to desulfurize 12 to 13. Utpal Bora of Tezpur University oxidized (Tetrahedron Lett. 2014, 55, 5029) the alcohol 14 to the aldehyde 15 with t-butyl hydroperoxide, using the inexpensive and reusable VOSO₄ as the catalyst. The oxidation of an alcohol to the acid is often car­ried out in two steps, alcohol to aldehyde and aldehyde to carboxylic acid. Kenneth B. Wagener of the University of Florida developed (Tetrahedron Lett. 2014, 55, 4452) a protocol for the direct oxidation of an alcohol 16 to the acid 17. Prodeep Phukan of Gauhati University devised (Tetrahedron Lett. 2014, 55, 5358) a catalyst-free procedure for the oxidation of a primary alcohol 18 to the ester 19. The aldehyde cor­responding to 18 (not illustrated) was also efficiently oxidized to 19. Katsuhiko Moriyama and Hideo Togo of Chiba University effected (Org. Lett. 2014, 16, 3812) the oxidative debenzylation of 20 to the ketone 21.

Scientific Research Activity

Summing up the results of scientific research activity for 2017, we can confidently say that NUST MISIS, based on the scientific po­tential and experience of its teaching and research staff, has achieved even more substantial gains in the field of fundamental and applied research. Through the development of laboratories, invitation of inter­nationally recognized researchers to the university, and participation in ambitious international scientific projects, the university continues ev­ery year to conduct even more research and development in disciplines that are both conventional and new for NUST MISIS. This article presents the main results of the research and technology and innovation efforts of the National University of Science and Technology MISIS (NUST MISIS) for 2017. The issues of inclusion in international ratings, university financing, results of the researchers’ publishing activi­ties, as well as the results of scientific and innovation efforts, have been covered here in detail.
