Asymmetric Formal Synthesis of (-)-Cephalotaxine via Palladium-Catalyzed Enantioselective Tsuji Allylation

Asymmetric synthesis of the pentacyclic alkaloid (-)-cephalotaxine was accomplished via palladium-catalyzed enantioselective Tsuji allylation for construction of the aza-containing tetrasubstituted stereogenic center (95% yield, 93% ee). The allyl enol carbonate precursor was prepared from Hanaoka’s ketone intermediate, which was formed by a novel formic acid promoted ring-expansion reaction.

Synthesis and characterization of some mixed-ligand picrate complexes of nickel(II) involving heterocyclic nitrogen donors

The present communication describes the synthesis of some mixed-ligand hexacoordinated picrato complexes of nickel(II) of the composition [Ni(PA)2(L-L)2], where PAH = picric acid and L-L = 2-aminoben-zothiazole (ABZT), 2-(2?-aminophenyl)benzothiazole (2?-AMPHBZT), 2-(3?-aminophenyl)benzothiazole (3?-AMPHBZT), bipyridine (bpy), o-phenanthroline (phen) or 2,6-bis(benzimidazyl)pyridine (BBZLPY). These complexes were obtained by the interaction of nickel(II) picrate with the corresponding ligands L-L in methanol. The resulting compounds have been characterized by elemental analyses, magnetic, molar conductance and decomposition temperature measurements, electron spin resonance, infrared and electronic spectral studies. All the complexes are thermally stable and behave as non-electrolytes. An octahedral structure has been tentatively proposed for these complexes.

Enantioselective Synthesis of Phthalides and Isochromanones via Heck?Matsuda Arylation of Dihydrofurans

In this communication, the enantioselective synthesis of phthalides and isochromanones is described through a new palladium-catalyzed Heck?Matsuda arylation/NaBH4-reduction/lactonization sequence of 2,3- and 2,5-dihydrofurans in good overall yields and excellent enantioselectivities (up to 98:2 er). This expeditious synthesis of chiral Heck lactol intermediates allowed the diversification of the strategy to obtain medicinally relevant chiral lactones, amines, and olefins. The natural product 3-butylphthalide was obtained in three steps with an overall yield of 33 % yield in 98:2 er.

Activation of H2O2 by chiral confined Bronsted acids: A highly enantioselective catalytic sulfoxidation

Confined chiral Bronsted acids are shown to catalyze asymmetric oxidations of sulfides to sulfoxides with hydrogen peroxide. The wide generality and high enantioselectivity of the developed method compare even to the best metal-based systems and suggest utility in other asymmetric oxidations.

(-)-Sparteine-mediated stereoselective directed ortho metalation of ferrocene diamides

The utility of (-)-sparteine-mediated directed ortho metalation (DoM) has been investigated in stereoselective preparation of planar chiral ferrocenes derived from 1,1?-N,N,N?,N?- tetraisopropylferrocenedicarboxamide (5). In the synthesis of C 2-symmetric analogs of 5, the protocol (base, solvent, and two-step DoM) was found to be crucial for obtaining high enantio- and diastereo-selectivities of the products. A variety of highly enantioenriched mono and doubly functionalized derivatives of 5 have been synthesized. The synthetic applications of these compounds as chiral ligands in asymmetric alkylation of aldehydes and asymmetric palladium-catalyzed allylic substitutions have been demonstrated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C34H28Cl2FeP2Pd, you can also check out more blogs about72287-26-4
