Synthesis of Chloroesters by the Cleavage of Cyclic and Acyclic Ethers using La(NO3)3 · 6H2O as a Mild and Efficient Catalyst under Solvent‐Free Conditions

Abstract A mild and an efficient synthesis of chloroesters is described by the reaction of cyclic and acyclic ethers with acid chlorides in the presence of a catalytic amount of La(NO3)3 · 6H2O under solvent‐free conditions, affording the corresponding chloroesters in excellent yields.

Lanthanum(III) Nitrate Hexahydrate: A Versatile Reagent for the Synthesis of Bis(indolyl) Methanes under Solvent‐Free Conditions

Abstract A mild and efficient synthesis of bis(indolyl) methanes by the reaction of indoles with various aldehydes at room temperature in the presence of a catalytic amount of a La(NO3)3 · 6H2O afforded the corresponding bis(indolyl) methanes in excellent yields under solvent‐free conditions.

First Asymmetric Total Synthesis of (R,E)-1-[4-(3-Hydroxyprop-1-enyl)phenoxyl]-3-methylbutane-2,3-diol

Abstract A new anti-inflammatory active phenylpropenoid, (R,E)-1-[4-(3-hydroxyprop-1-enyl) phenoxyl]-3-methylbutane-2,3-diol (1), isolated from the stem wood of Zanthoxylum integrifoliolum, has been synthesized for the first time using commercially available 4-hydroxy benzaldehyde (2). The key step involves the Sharpless asymmetric dihydroxylation of olefin (3).
