Inositol-based

An interesting example of the effectiveness of different reagents for 0-nitration can be seen during the synthesis of neo-inositol-based nitrate ester explosives. l,4-Dideoxy-l,4-dinitro-neo-inositol (15), a compound readily prepared from the condensation of nitromethane and glyoxal in the presence of base,undergoes conversion to the tetranitrate ester (16) on... [Pg.92]

The D-tf//o-inositol-based cyclic sulfate 53 has been reduced with sodium hydrogen telluride to the protected conduritol (Equation 13) <2000EJ01285>. [Pg.180]

Oxygen atoms in the tetrahydrofuran rings embedded in inositol-based tris(spirotetrahydrofuranyl)ionophores were useful as chelation sites towards selective alkali metal ion binding and as a result rodlike supramolecular ionic polymer frameworks were prepared and analyzed in this study <01JA4974>. The temperature and viscosity dependence of the spin-directed stereoselectivity of the Patemo-Buchi photocycloaddition reactions between 2,3-dihydrofuran and benzaldehyde were studied <01 AG(E)4684>. [Pg.151]

Base-catalyzed nitromethane cyclizadonof the thaldehyde generated by periodate oxidation of 1,3-O-cyclohexyhdene-myo-inositol affords the nitrodiol with l,4/3,3,5-coti iguration This is converted into the ct-marmosidase inhibitor, marmostadn A fEq 3 60 ... [Pg.49]

The simultaneous analysis of orthophosphate, glycerol phosphates, and inositol phosphates has been achieved by spectrophotometric analysis of the molybdovanadate complexes. Also, a sensitive and selective chemiluminescent molecular emission method for the estimation of phosphorus and sulphur is described, which is based on passing solutions into a cool, reducing, nitrogen-hydrogen diffusion flame. For organic compounds it was usually necessary to prepare test solutions by an oxygen-flask combustion technique. [Pg.278]

Base-catalyzed nitromethane cyclization of the dialdehyde generated by periodate oxidation of 1,2-O-cyclohexylidene-myo-inositol affords the nitrodiol with 1,4/2,3,5-configuration. This is converted into the a-mannosidase inhibitor, mannostatin A (Eq. 3.60).98... [Pg.49]

In a study of isomerization in some partially acetylated derivatives of mt/o-inositol, weak bases were found to catalyze migration between all of the oxygen atoms, and cis and trans migrations occurred with almost equal facility.546 Equilibration of DL-2-O-acetyl-... [Pg.106]
