, p. 834 - 835 (2006)
A new water soluble 2,2-bifunctionalized spin label (2,2E-BSL) having pyrrolidine nitroxide moiety was synthesized starting from a nitro compound with two hydroxymethyl group converted to the linkers of the 2,2E-BSL, and was applied to label troponin C (TnC). Labeled TnC through two linkages were successfully isolated, and 2,2E-BSL was proved to be immobilized on TnC by EPR measurement. Copyright

Synthesis of 2,3-bis(hydroxymethyl)butane-1,2,3,4-tetraol is of great interest because of its utility as a potential precursor to new dendrimers, in the preparation of unnatural lipids, and in the synthesis of open-framework coordination polymers. Synthesis of this new six-hydroxyl compound is achieved in four steps from commercially available starting materials. In this process, a new olefin-forming cascade reaction was discovered.

Indium-mediated reaction of 1-bromo-1-nitroalkanes with aldehydes: Access to 2-nitroalkan-1-ols

experimental part, p. 5190 - 5196 (2010/11/02)
A novel method for the preparation of 2-nitroalkan-1-ols by an indium-promoted reaction of bromonitromethane with a variety of aldehydes is reported. The reaction was also performed with 2-bromo-2-nitropropanes to afford 2,2-dialkyl-2-nitroalkan-1-ols. The use of chiral sugar-derived aldehydes furnished the corresponding 2-nitroalkan-1-ols with excellent stereoselectivity. The utility of the novel sugar-derived 2,2-dialkyl-2-nitroalkan-1-ols for the preparation of branched iminosugar derivatives was demonstrated by the preparation of a hydroxymethyl branched polyhydroxylated azepane.

, p. 3859 - 3866 (2008/09/21)
An efficient total synthesis of the S1P1 agonist, KRP-203, is described. The key step involves the conjugate addition of diethyl acetamidomalonate to a styrene compound to give the core structure of KRP-203. Multigram quantities of the targeted KRP-203, sufficient for several biological studies, were obtained in six steps with an overall yield of 58%.

Five protected submonomers for peptoid synthesis were prepared, including N(in)-BOC-tryptamine, O-t-butyl tyramine, PMC-guanidino- propylamine, 6-amino-6-deoxy-D-galactopyranose diacetonide, and 5-amino-2,2- dimethyl-1,3-dioxane. The first three mimic nat
Preparation and antiparasitic activity of new imidazoles bearing dioxane or hexahydropyrimidine moiety

, p. 709 - 714 (2007/10/02)
5-Nitro-1,3-dioxane and 5-nitrohexahydropyrimidine salts are found to be suitable nucleophiles for S(RN)1 reactions. From C-alkylation products, base-promoted nitrous acid elimination and acid-catalyzed cleavage of the resulting acetals afford new compounds. Only the imidazole derivatives exhibit significant amoebicide and trichomonacide activities. Structure-activity relationships are discussed.
