A novel C-C bond formation by Baylis-Hillman type reaction mediated by SmI2: An effective approach to α-hydroxyalkylacrylamide synthesis

α-Bromoacrylamides (1) reacted with aldehydes or ketones, in the presence of SmI2 at - 78 °C in THF, within 5 min to produce Baylis-Hillman type reaction products (2) through an anionic process using vinylsamarium Grignard species in good yield

Diastereoselective Photoredox-Catalyzed [3 + 2] Cycloadditions of N-Sulfonyl Cyclopropylamines with Electron-Deficient Olefins

A highly diastereoselective, visible-light-induced [3 + 2] cycloaddition between N-sulfonyl cyclopropylamines and electron-deficient olefins is reported. The reactions proceed via the oxidation of a sulfonamide aza-anion by an organic photocatalyst to generate a nitrogen-centered radical. Strain-induced ring opening and intermolecular addition to the olefin generate an intermediate carbon-centered radical that is reduced to an anion prior to 5-exo cyclization. This enables a highly diastereoselective construction of trans-cyclopentanes possessing synthetically useful functional groups.

Synthesis of Phenanthridine and Quinoxaline Derivatives via Copper-Catalyzed Radical Cyanoalkylation of Cyclobutanone Oxime Esters and Vinyl Azides

A copper-catalyzed radical cyclization of cyclobutanone oxime esters and vinyl azide is described. This method provides facile access to cyanoalkyl-substituted phenanthridines and quinoxalines with excellent isolated yields. Moreover, these reactions proceed under mild conditions with a board substrate scope and excellent functional group tolerance.

Potassium Base-Catalyzed Michael Additions of Allylic Alcohols to α,β-Unsaturated Amides: Scope and Mechanistic Insights

We report herein the first KHMDS-catalyzed Michael additions of allylic alcohols to α,β-unsaturated amides through allylic isomerization. The reaction proceeds smoothly in the presence of only 5 mol% of KHMDS to afford a variety of 1,5-ketoamides in high yields. Mechanistic investigations, including experimental and computational studies, reveal that the KHMDS-catalyzed in-situ generation of the enolate from the allylic alcohol through a tunneling-assisted 1,2-hydride shift is the key to the success of this transformation. (Figure presented.).

An efficient approach for the synthesis of new (±)-coixspirolactams

Coixspirolactams, spiro[oxindole-γ-lactones], are found in adlay seeds and exhibit anticancer activity. A novel synthetic methodology was developed to enable an easy access to (±)-coixspirolactam A and a large number of new coixspirolactams in excellent overall yields. The exquisite exploitation of formamide reactivity was essential for the construction of oxindole and lactone scaffolds. This journal is

Rh(i)-Catalyzed regioselective arylcarboxylation of acrylamides with arylboronic acids and CO2

The first Rh(i)-catalyzed regioselective arylcarboxylation of electron-deficient acrylamides with arylboronic acids under atmospheric pressure of CO2 has been developed. A range of acrylamides and arylboronic acids were compatible with this reaction under redox-neutral conditions, leading to a series of malonate derivatives that are versatile building blocks in organic syntheses.

Disulfides as Sulfonylating Precursors for the Synthesis of Sulfone-Containing Oxindoles

The first facile one-pot synthesis of sulfone-containing oxindoles with easily accessible disulfides as the sulfonylating precursors is described. This reaction occurs smoothly under transition metal-free conditions and shows excellent functional group tolerance, allowing the facile and efficient green synthesis of various sulfone-containing oxindoles in aqueous solution. Preliminary mechanistic studies reveal that both water (H2O) and potassium persulfate (K2S2O8) can be the oxygen source of the sulfone groups in the products. (Figure presented.).
