A.P. Hagen's Inorganic Reactions and Methods: The Formation of Bonds to PDF

For the 1st time the self-discipline of recent inorganic chemistry has been systematized in keeping with a plan developed via a council of editorial advisors and specialists, between them 3 Nobel laureates (E. O. Fischer, H. Taube and G. Wilkinson). instead of generating a set of unrelated assessment articles, the sequence creates a framework which displays the inventive capability of this clinical self-discipline.

Example text

The C(2)–N bond of the aziridine 35 36 Aziridines and Azirines: Monocyclic is regiospecifically cleaved by the bromide ion from MgBr2 or the chloride ion from TMSCl via an SN2 process as in 330, and then an intramolecular cyclization by the urea amide nitrogen of 331 gives the corresponding imidazolidinone 332 which corresponds to overall retention of the configuration at C-2 of the orginal aziridine 329 (Scheme 85). 3 Ring expansion with nitriles A direct and efficient route to imidazoline and pyrrolidine derivatives using copper(II) triflate-mediated [3þ2] cycloaddition of various aryl, alkyl, and cycloalkyl N-tosylaziridines with nitriles and olefins as dipolarophiles has been reported <2006TL5399>.

N-Tosyl-protected 2-substituted aziridines 307 underwent regioselective addition of the Pd–TMM complex at the least-hindered site and furnished the functionalized piperidines 308 (TMM ¼ trimethylenemethane). This technique provides an expedient route to enantiopure 2-piperidines because the precursor aziridines are readily prepared in enantiomerically pure from the corresponding amino acids (Scheme 79) <1992SL41>. 2 Grignard addition–cyclization reaction for piperidine synthesis More recently, a stepwise formal [3þ3] cycloaddition sequence via a Grignard addition–cyclization reaction leads to a much improved piperidine synthesis <2005OL2993>.

464) (Scheme 120) <1999TL6503>. There are reports on the use of a Cu(I) complex of ferrocenyldiimine 465 to facilitate nitrene transfer to olefins <1998SL617>. Of particular interest for industrial applications, these reactions can also be efficiently catalyzed by 53 54 Aziridines and Azirines: Monocyclic copper-exchanged zeolite (CuHY) in acetonitrile. , 466). For example, styrene 467 was converted to the corresponding aziridine 468 in 82% yield and 44% ee. The solid-supported catalysts can be easily removed from the reaction mixture, washed, and reused without detrimental effect to catalytic or enantioinductive activity (Scheme 121) <1998CC1601>.
