An Ugi reaction in the total synthesis of (-)-dysibetaine.

Jerry Isaacson et al.

Angewandte Chemie (International ed. in English), 48(10), 1845-1848 (2009-01-29)

(-)-Dysibetaine has been synthesized in 11 steps from readily available L-malic acid (see scheme). The key step is a unique Ugi 4-center-3-component cyclization reaction, where an ester group acts as the carboxylic acid component. The use of 1,1,1,3,3,3-hexamethyldisilazane as an

Gas chromatography-mass spectrometry of the trimethylsilyl (oxime) ether/ester derivatives of cholic acids: their presence in the aquatic environment.

A Sebok et al.

Journal of chromatography. A, 1211(1-2), 104-112 (2008-10-14)

This paper presents a derivatization, mass fragmentation study relating to the most common six cholic acids, such as cholic, lithocholic, chenodeoxycholic, ursodeoxycholic, 3-hydroxy,7-ketocholanic and dehydrocholic acids, identified and quantified as pollutants in the aquatic environment at the first time. Derivatizations

Reactions of (-)-sparteine with alkali metal HMDS complexes: conventional meets the unconventional.

Natalie M Clark et al.

Chemical communications (Cambridge, England), (39)(39), 5835-5837 (2009-09-30)

'Conventional' (-)-sparteine adducts of lithium and sodium 1,1,1,3,3,3-hexamethyldisilazide (HMDS) were prepared and characterised, along with an unexpected and 'unconventional' hydroxyl-incorporated sodium sodiate, [(-)-sparteine x Na(mu-HMDS)Na x (-)-sparteine](+)[Na(4)(mu-HMDS)(4)(OH)](-)--the complex anion of which is the first inverse crown ether anion.
