Ferrocenyl diphosphines R2PF-P(R?)2 are effective, tunable ligands for the iridium catalyzed enantioselective hydrogenation of N-aryl imines in the presence of iodide and acid promoters. Structure-activity/selectivity correlations were found for the hydrogenation of N-(2-ethyl-6-methylphenyl)-N-(1?-methoxymethyl)-ethylidene-amine (MEA-imine) and for 2,3,3-trimethylindolenine (TMI). Extremely high catalytic activity and moderate to good enantioselectivity were observed for the MEA imine using a catalyst generated in situ from [Ir(cod)Cl]2 and (R)-(S)-PPF-P(3,5-Xyl)2 (xyliphos). With the same type of catalysts, several other N-aryl imines can be hydrogenated with enantioselectivities between 31 and 96%, albeit with lower catalyst activities.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

Gold(I) complexes of overall formula LAuCl (L = various methylpyridines) are non-conducting in acetone. X-ray structure analyses show that the solid state structure of the corresponding complex 1 (L = 2-picoline) is molecular; the 3-picoline derivative 2 is however ionic (L2Au)+(AuCl2)-. 3-Picoline forms a molecular complex LAuC6F5 (3) and also the ionic (L2Au)+(SbF6)- (4). Complexes 1, 2 and 4 display short Au…Au contacts, leading to chains of gold atoms; additionally, complexes 3 and 4 show weak Au…F contacts. The (3-picoline)-gold(III) complex trans-(L2AuCl2)+(SbF6)- (5) was obtained as a by-product; it too contains short Au…F contacts.

A cooperative system comprising of a lithium Lewis acid and amine base significantly enhances the rate of the conjugate addition of a wide array of amines to maleimides. This operationally simple, scalable method provides mono-addition products in high yields and purity. This conjugation was successfully applied to the kinase inhibitor crizotinib in a chemoselective ligation to create novel fluorescent probe. (Figure presented.).

Reconciliation of standard entropies Delta0TSmo(cal) derived from calorimetric and thermophysical property studies with standard entropies Delta0TSmo(stat) derived with assigned vibrational spectra and the methods of statistical mechanics is used to demonstrate consistency between thermophysical properties for the six dimethylpyridines (Chemical Abstracts registry numbers: 2,3-dimethylpyridine, 583-61-9; 2,4-dimethylpyridine, 108-47-4; 2,5-dimethylpyridine, 589-93-5; 2,6-dimethylpyridine, 108-48-5; 3,4-dimethylpyridine, 583-58-4; 3,5-dimethylpyridine, 591-22-0). Properties considered include the critical temperature, critical pressure, vapor pressure, heat capacities of the solid and liquid, second and third virial coefficients, enthalpies of vaporization, vibrational assignment, and methyl group rotational barrier. The temperature-dependent properties are shown to be consistent over the entire temperature range from near T = 250 K to T = 650 K ( ? 0.95·Tc, where Tc denotes the critical temperature). The analyses validate the methods and results reported previously, which provided the information required to derive the temperature-dependent properties to near Tc, i.e. into the temperature and pressure range typical of petroleum processing conditions. Sensitivities of Delta0TSmo(stat) to errors in the vibrational assignment and to the size of methyl group rotational barriers are discussed. Vibrational assignments for vapor-phase fundamentals at low wave number for 2,3-dimethylpyridine and 3,4-dimethylpyridine are shown to be in error and are corrected.

Tubulin binding compounds represent one of the most attractive targets for anticancer drug development. They broadly fall into two categories viz., tubulin polymerization inhibitors, which block microtubule growth and destabilize microtubules like vinca alkaloids and cryptophycins, and the others, which polymerize microtubules into hyperstable forms represented by family of taxanes. In this context, we aimed at design and synthesis of cryptophycins based macrocyclic depsipeptides, which are synthetically more accessible, however have the basic information to target tubulins and establish structure activity relationship (SAR). Thus, a new class of cryptophycins based marocyclic depsipeptides with a truncated epoxide chain were synthesized as potential tubulin inhibitors. The resultant lead analogues 15a and 16a exhibited good anti-cancer activity, induced apoptosis, caused block/delay in cell cycle as well as significantly reduced the expression of alpha- and beta-tubulins. Molecular modelling studies show that 15a and 16a bind in the same domain as that of cryptophycins.
