Page/Page column 24, (2015/07/07)
The present invention is directed to 5-heteroarylmorpholine derivatives and their use in the inhibition of HIV protease, the inhibition of HIV replication, the prophylaxis of infection by HIV, the treatment of infection by HIV, and the prophylaxis, treatment, and delay in the onset or progression of AIDS. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
Nature-inspired total synthesis of (-)-fusarisetin A
Xu, Jing,Caro-Diaz, Eduardo J. E.,Trzoss, Lynnie,Theodorakis, Emmanuel A.
, p. 5072 - 5075 (2012/05/07)
A concise, protecting group-free total synthesis of (-)-fusarisetin A (1) was efficiently achieved in nine steps from commercially available (S)-(-)-citronellal. The synthetic approach was inspired by our proposed biosynthesis of 1. Key transformations of our strategy include a facile construction of the decalin moiety that is produced via a stereoselective IMDA reaction and a one-pot TEMPO-induced radical cyclization/aminolysis that forms the C ring of 1. Our route is amenable to analogue synthesis for biological evaluation.
Synthesis of histidinoalanine: A comparison of β-lactone and sulfamidate electrophiles
Taylor, Carol M.,De Silva, Samanthi Thabrew
, p. 5703 - 5708 (2011/09/16)
Previous syntheses of histidinoalanine (HAL) have led to mixtures of regioisomers and/or stereoisomers. For example, opening of N-Cbz-d-serine- β-lactone (6) with Boc-l-His-OMe (5) gave a 2:1 mixture of τ- and π-regioisomers. The sulfamidate 10, derived f
Orthogonally protected glycerols and 2-aminodiols: Useful building blocks in heterocyclic chemistry
Ollivier, Anthony,Goubert, Marlene,Tursun, Ahmatjan,Canet, Isabelle,Sinibaldia, Marie-Eve
experimental part, p. 108 - 126 (2010/10/03)
The efficient synthesis of orthogonally protected glycerols, 2-aminopropane-1,3-diols and 2-aminobutane-1,4-diols that can constitute useful tools in heterocyclic chemistry, is reported. These interesting tri-functionalized small synthons were easily prepared from serine or aspartic acid. In addition, these substrates can be readily transformed into their iodide derivatives in very good yields. ARKAT USA, Inc.

Two syntheses of (-)-kainic acid via highly stereoselective zinc-ene cyclizations
Chalker, Justin M.,Yang, Ao,Deng, Kai,Cohen, Theodore
, p. 3825 - 3828 (2008/02/12)
Two concise, high-yielding syntheses of enantioenriched (-)-kainic acid are presented. Both routes feature a Pd-catalyzed Zn-ene cyclization that proceeds with complete diastereoselectivity. The key step can be carried out on a multigram scale, and the ov
