Uses

Used in Organic Synthesis:
DBI is used as a chiral auxiliary in organic synthesis for its ability to induce asymmetry in the formation of optically pure compounds. This property is highly valuable in the production of enantiomerically pure substances, which are essential in various applications, including pharmaceuticals and agrochemicals.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, DBI serves as a starting material for the synthesis of complex organic molecules with potential therapeutic applications. Its role in facilitating asymmetric synthesis is particularly important in the development of drugs with specific stereochemistry, which can influence the efficacy and safety of medications.
Used in Agrochemical Industry:
DBI is also utilized in the agrochemical industry as a precursor for the synthesis of biologically active compounds. Its ability to participate in asymmetric synthesis contributes to the development of agrochemicals with targeted effects, reducing potential environmental impacts and improving the overall efficiency of these products.
Used in Asymmetric Synthesis:
DBI is employed in asymmetric synthesis as a key building block, enabling the creation of enantiomerically pure compounds with specific spatial arrangements. This is crucial in various chemical processes, as the stereochemistry of a molecule can significantly affect its reactivity, stability, and biological activity.

A Chiral Phosphoramidite Reagent for the Synthesis of Inositol Phosphates

There is a paucity of chiral phosphoramidite reagents or chiral catalysis methods for the synthesis of biologically relevant inositol phosphates. A new C2-symmetrical chiral phosphoramidite has been developed and successfully applied to the syn

H2SO4-silica: An eco-friendly heterogeneous catalyst for the differential protection of myo-inositol hydroxyl groups

There is enormous interest in myo-inositol derivatives as they serve as precursors for the synthesis of several biologically important phosphoinositols, natural products, catalyst, supramolecular architectures etc. However the presence of six secondary hy

A simple and practical synthetic procedure for the versatile intermediates, (±)-1,2:5,6-di-O-isopropylidene-myo-inositol and (±)-6-O-benzoyl-1,2:4,5-di-O-isopropylidene-myo-inositol, is described.

Practical divergent synthesis of all possible regioisomers of myo-inositol trisphosphates

The synthesis of all possible 12 regioisomers of IP3, some of which are implicated as second messengers in cellular signalling, is accomplished from myo-inositol via its tribenzoate derivatives (IBz3) as the key intermediates.

Unambiguous Total Synthesis of the Enantiomers of myo-Inositol 1,3,4-Trisphosphate: 1L-myo-Inositol 1,3,4-Trisphosphate Mobilizes Intracellular Ca2+ in Limulus Photoreceptors

Syntheses of the enantiomers of myo-inositol 1,3,4-trisphosphate are described. 1,4-Di-O-allyl-myo-inositol was regioselectively p-methoxybenzylated at the 3-position to give 1,4-di-O-allyl-3-O-(p-methoxybenzyl)-myo-inositol followed by benzylation of the remaining free hydroxyl groups to give the key intermediate 1,4-di-O-allyl-2,5,6-tri-O-benzyl-3-O-(p-methoxybenzyl)-myo-inositol.Removal of the p-methoxybenzyl and allyl groups gave 2,4,5-tri-O-benzyl-myo-inositol which was-phosphitylated with bis(benzyloxy)(diisopropylamino)phosphine to give the fully protected trisphosphite triester.Oxidation using tert-butyl hydroperoxide gave 2,5,6-tri-O-benzyl-1,3,4-tris(dibenzylphospho)-myo-inositol, and deprotection using sodium in liquid ammonia gave racemic myo-inositol 1,3,4-trisphosphate.Deprotection of the key intermediate 1,4-di-O-allyl-2,5,6-tri-O-benzyl-3-O-(p-methoxybenzyl)-myo-inositol by isomerization of allyl groups followed by mild acid hydrolysis gave 2,4,5-tri-O-benzyl-1-O-(p-methoxybenzyl)-myo-inositol, which was converted to the diastereoisomeric bis-(-)-camphanates.The diastereoisomers were separated by column chromatography and the camphanates and the p-methoxybenzyl group removed by saponification and acid hydrolysis, respectively, for each diastereoisomer to give the enantiomers of 2,4,5-tri-O-benzyl-myo-inositol.The absolute configurations of the latter were established by conversion of 1L-2,5,6-tri-O-benzyl-3-O-(p-methoxybenzyl)-myo-inositol to the known 1L-1,2,4,5,6-penta-O-benzyl-myo-inositol.Phosphorylation and deblocking gave the D- and L-enantiomers of myo-inositol 1,3,4-trisphosphate.Biological evaluation in Limulus photoreceptors showed that 1L-myo-inositol 1,3,4-trisphosphate was much more active than the D-enantiomer, producing repetitive bursts of depolarization due to mobilization of intra cellular calcium.

Regioselective functionalizations and conformational studies of di-O-isopropylidene-myo-inositol derivatives

(+/-)-1,2:4,5-Di-O-isopropylidene-myo-inositol (5) and (+/-)-1,2:5,6-di-O-isopropylidene-myo-inositol (6) could be regioselectively functionalized in reactions including alkylation, acylation, and silylation at HO-3 in preference to HO-6 and HO-4, respectively, under specific conditions.The presence of intramolecular hydrogen bonding was evident in IR and 1H NMR spectra, and the HO-3 group was identified as the hydrogen-bonding donor in 5 and 6.In their crystalline states, diol 5 prefers a chair conformation and diol 6 a twist boat (skew) conformation.Both compounds appear to have substantial populations of chair conformations in the gas and solution phases, on the basis of the MM-2 energy minimizations and comparisons of vicinal coupling constants observed in the 1H NMR spectra (in CDCl3 and Me2SO-d6) and calculated from the crystal and MM-2 conformations.It is suggested as an explanation for the observed selectivities that the kinetic acidity of the HO-3 group may be enhanced through its intramolecular hydrogen bonding with the cis-vicinal oxygen, or the nucleophilicity of the 3-alkoxide may be enhanced due to its interaction with the cis-vicinal oxygen in a manner similar to the through-space α-effect.
