Activation of alcohols with carbon dioxide: Intermolecular allylation of weakly acidic pronucleophiles

The direct coupling of allyl alcohols with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished via activation of C-OH bonds with CO2. The in situ formation of carbonates from alcohols and CO2 facilitates oxidative addition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong base activates nucleophiles toward the reaction with the π-allylpalladium electrophile. Overall, this atom economical reaction provides a new C-C bond without the use of an external base and generates water as the only byproduct.

An expedient protocol for cyclopentenone annulation

A convenient and general protocol for the cyclopentenone annulation process is described.

An efficient synthesis of α-Cuparenone

Synthesis of α-Cuparenone is described. The key step involved are photorearrangement of α-halo arylketone (4) to 1-methyl-1-(p-tolyl)acetic acid (5) and extremely mild, essentially neutral, room temperature/3-aza-claisen reaction of N-allylamide (6).
