The total synthesis of the carbohydrate portion (penta-and tetrasaccharides) of steroidal saponins, isolated from Calamus insignis, is reported. A simple route is followed, starting from commercially available D-glucose and L-rhamnose, through high-yielding protecting group manipulation strategies. Sulfuric acid immobilized on silica (H2SO 4/silica) was used as an effective Broensted acid source in conjunction with N-iodosuccinimide for activation of thioglycosides or alone for trichloroacetimidate donors in key glycosylation steps.

Related Products of 3301-94-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.3301-94-8, Name is 6-Butyltetrahydro-2H-pyran-2-one, molecular formula is C9H16O2. In a patent, introducing its new discovery.

Previous studies have shown that delta-octalactone is an important component of the tsetse-refractory waterbuck (Kobus defassa) repellent odour blend. In the present study, structure-activity comparison was undertaken to determine the effects of the length of the side chain and ring size of the lactone on adult Glossina pallidipes and Glossina morsitans morsitans. The responses of the flies to each compound were studied in a two-choice wind tunnel. Increasing the chain length from C3 (delta-octalactone) to C4 (delta-nonalactone) enhanced repellency to both species (G. pallidipes from 60.0 to 72.0%, and G. m. morsitans from 61.3 to 72.6%), while increasing the ring size from six (delta-octalactone) to seven members (epsilon-nonalactone) changed the activity from repellency to attraction that was comparable to that of the phenolic blend associated with fermented cow urine (p > 0.05). Blending delta-nonalactone with 4-methylguaiacol (known tsetse repellent) significantly (p < 0.05) raised repellency to 86.7 and 91.7% against G. pallidipes and G. m. morsitans respectively. Follow-up Latin Square Designed field studies (Shimba hills in coastal areas in Kenya) with G. pallidipes populations confirmed the higher repellence of delta-nonalactone (with/without 4-methylguaiacol) compared to delta-octalactone (also, with/without 4-methylguaiacol). The results show that subtle structural changes of olfactory signals can significantly change their interactions with olfactory receptor neurons, and either shift their potency, or change their activity from repellence to attraction. Our results also lay down useful groundwork in the development of more effective control of tsetse by 'push', 'pull' and 'push-pull' tsetse control tactics.

Synthesis of the 2,2?-dipyridylamine derivatives di-2- pyridylaminomethylbenzene 1, 1,2-bis(di-2-pyridylaminomethyl)benzene 2, 1,3-bis(di-2-pyridylaminomethyl)benzene 3, 2,6-bis(di-2-pyridylaminomethyl) pyridine 4, 1,4-bis(di-2-pyridylaminomethyl)benzene 5, and 1,3,5-tris(di-2- pyridylaminomethyl)benzene 6 are reported together with the single-crystal X-ray structures of 2, 3, and 5. Reaction of individual salts of the type AgX (where X = NO3-, PF6-, ClO4 -, or BF4-) with the above ligands has led to the isolation of thirteen Ag(i) complexes, nine of which have also been characterised by X-ray diffraction. In part, the inherent flexibility of the respective ligands has resulted in the adoption of a range of coordination arrangements. A series of liquid-liquid (H2O/CHCl3) extraction experiments of Ag(i) with varying concentrations of 1-6 in the organic phase have been undertaken, with the counter ion in the aqueous phase being respectively picrate, perchlorate and nitrate. In general, extraction efficiencies for a given ionophore followed the Hofmeister order of picrate > perchlorate > nitrate; in each case the tris-dpa derivative 6 acting as the most efficient extractant of the six systems investigated. Competitive seven-metal bulk membrane transport experiments (H2O/CHCl 3/H2O) employing the above ligands as the ionophore in the organic phase and equimolar concentrations of Co(ii), Ni(ii), Zn(ii), Cu(ii), Cd(ii), Pb(ii) and Ag(i) in the aqueous source phase were also undertaken, with transport occurring against a pH gradient. Under the conditions employed 1 and 5 yielded negligible transport of any of the metals present in the source phase while sole transport selectivity for Ag(i) was observed for 2-4 and 6.

The remaining positions are occupied by two nitrogen atoms of the pseudo-halide ligands. The magnetic susceptibility measurements at ambient pressure have revealed that compound 1 exhibits an incomplete spin crossover behaviour (T1/2 ? 88 K), whereas compound 2 remains in the high-spin configuration. Pressure studies performed on compound 1 have shown virtually complete spin crossover behaviour as pressure attains 6.5 kbar.
