✦ Synopsis

The reaction of chromium alkyl(alkoxy)carbenes with propargylic alcohols has been investigated under thermal and ultrasound conditions. Both sets of developed conditions provide rapid access to alkyl-substituted ~-lactone products, which also possess enol ether functionality, from readily available starting materials.

The carbanion generated from the methyl (pyrrolidino) chromium carbene complex 6a reacts with a variety of alkylating reagents to provide good to high yields of monoalkylated products. The alkylation reactions of the amino carbene complex were found to be significantly more efficient than alkoxy car
