Iridium-Catalyzed Intramolecular Oxidative Cyclization of Alkenyl Amides and Alkenoic Acids

An iridium/dppf complex efficiently catalyzed the oxidative cyclization of N sulfonyl alkenyl amides and alkenoic acids. Electron deficiena?t alkenes were effective as sacrificial hydrogen acceptors. High selectivity of the oxidative cyclization over the

Pd-catalyzed 5-endo-trig-type cyclization of β,γ-unsaturated carbonyl compounds: An efficient ring closing reaction to give γ-butenolides and 3-pyrrolin-2-ones

The 5-endo-trig-type cyclization has been performed using a Pd-bis(isoxazoline) catalyst. The present cyclization of β,γ- unsaturated carbonyl compounds gave γ-butenolides and 3-pyrrolin-2-ones in good to excellent yields.

Transition Metal Catalyzed Radical Cyclization: New Preparative Route to γ-Lactams from Allylic Alcohols via the -Sigmatropic Rearrangement of Allylic Trichloroacetimidates and the Subsequent Ruthenium-Catalyzed Cyclization of N-Allyltrichloroacetamides

A sequence of reactions including -sigmatropic rearrangement of allyl trichloroacetimidates (Overman rearrangement) followed by ruthenium-catalyzed cyclization of N-allyltrichloroacetamides provided a novel method for preparing trichlorinated γ-lactams from allylic alcohols.No δ-lactam was formed as a byproduct.The cyclization of secondary N-allyltrichloroacetamides proceeded with good diastereoselectivity.Two types of tandem cyclizations to form bicyclic lactams took place in the cyclization of N-allyltrichloroacetamides from geraniol and linalool.
