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.

Toward synthesis of carbasugars (+)-gabosine C, (+)-COTC, (+)-pericosine B, and (+)-pericosine C

Asymmetric total synthesis of (+)-gabosine C, (+)-pericosine B, and (+)-pericosine C has been reported from readily available d-(-)-isoascorbic acid and d-ribose involving Grubbs ring closing metathesis, Morita-Baylis-Hillman (MBH) reaction, and Luche reduction.

Lanthanum(III) nitrate hexahydrate catalyzed chemoselective thioacetalization of aldehydes

A wide variety of cyclic and acyclic dithioacetals have been prepared chemoselectively from their corresponding aldehydes with 1,3-dithiol and ethanethiol using catalytic amounts of lanthanum(III) nitrate hexahydrate as a catalyst at room temperature. †IICT Communication # 061103.
