Asymmetric hetero-ene reactions of trimethylsilyl enol ethers catalyzed by tridentate Schiff base chromium(III) complexes.

Bismuth Triflate Catalyzed Allylation of Acetals: A Simple and Mild Method for Synthesis of Homoallyl Ethers

The allylation of acetals using allyltrimethylsilane is efficiently catalyzed by bismuth triflate (1.0 mol%). The reaction proceeds smoothly at room temperature to afford the corresponding homoallyl ether in good yield. The mild reaction conditions, the low toxicity of bismuth salts, and the high catalytic efficiency of the system make this procedure particularly attractive for large-scale synt...

Iron-catalyzed direct α-arylation of ethers with azoles.

The direct α-arylation of cyclic and acyclic ethers with azoles has been achieved, which features a novel iron-catalyzed cross-dehydrogenative coupling (CDC) process. This practical oxidative method allowed the efficient C2-alkylation of a variety of (benzo)azoles constituting straightforward access to heterocycles of utmost medicinal significance and highlighting the convenient use of feedstoc...

Addition of organochromium reagents to heteroaryl aldehydes. Synthesis of heteroaryl substituted bis-allyl ethers and homoallyl ethers.

Heteroaryl substituted allyl and homoallyl alcohols were synthesised with two different method. Synthesis of bis-allyl ethers and homoallyl ethers were carried out via reaction of allyl bromide with allyl alcohols and homoallyl alcohols, respectively. [2.3]-Wittig Rearrangement reactions of heteroaryl substituted bis-allyl ethers were investigated using GC/MS techniques. In these reactions two ...
