Herein, we disclose an interesting iron-catalyzed approach for the carbonylation of a tertiary carbon radical. The tertiary carbon radical generated from a 1,5-hydrogen atom transfer can be captured by CO gas smoothly. Various six-membered lactams were constructed chemo-selectively in high yields.
THE CLAISEN REARRANGEMENT USING β-ALKYLTHIO-β,γ-UNSATURATED ALCOHOLS. A NEW METHOD FOR THE PREPARATION OF FURANS AND γ-OXOCARBOXYLIC ESTERS

Various furans and γ-oxocarboxylic esters were prepared by the pivalic acid-promoted Claisen rearrangement using β-alkylthio-β,γ-unsaturated alcohols followed by the treatment of the rearrangement products with an acid catalyst such as hydrochloric acid o
