Ferrier sulfamidoglycosylation of glycals catalyzed by nitrosonium tetrafluoroborate allowed the preparation of hydroxysulfamide glycosides in good yields with a good α stereoselectivity. A variety of mono-saccharide derivatives was synthesized using this

In this paper, we report the regioselective synthesis of 3,5-disubstituted isoxazoles by 1,3-dipolar cycloaddition between alkynyl dipolarophiles and nitrile oxide dipoles generated in-situ from O-silylated hydroxamic acids in the presence of trifluoromethanesulfonic anhydride and NEt3. Thanks to the mild, metal-free and oxidant-free conditions that this strategy offers, the reaction was successfully applied to a wide variety of alkynyl dipolarophiles, demonstrating the tolerance of this approach to diverse functional groups. In particular, we have shown that the method was compatible with biological molecules such as peptides and peptide nucleic acids (PNA). This protocol constitutes another example of metal-free 1,3-dipolar cycloaddition leading to the regioselective formation of isoxazoles.

The vinylogous anomeric effect in 3-alkyl-2-chlorocyclohexanone oximes and oxime ethers
Denmark,Dappen,Sear,Jacobs
, p. 3466 - 3474 (2007/10/02)
A series of trans-3-alkyl-2-chlorocyclohexanones, 2(methyl, ethyl, isopropyl, and tert-butyl), have been prepared and shown to exist predominantly in the diequatorial chair conformation except the tert-butyl derivative which prefers a twist-boat. Formatio
