, p. 4655 - 4658 (2019/05/09)
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 reactions of trialkylstannylmethyllithium with α,β-epoxy ketones afforded mainly cyclopropanols, while α-chloro ketones afforded allyl alcohols and/or cyclopropanols, in varying amounts depending upon the molar ratio of the reagent to the substrate.
REACTIVITE DU DERIVE LITHIE ISSU DU DIOXOLANNE DU LEVULATE DE TRIMETHYLSILYLE VIS-A-VIS DES DERIVES CARBONYLES: UNE METHODE DIRECTE D'OLEFINATION DES ALDEHYDES AROMATIQUES ET DES CETONES

At -60 deg C and in ether, the organolithium reagent produced by trimethylsilyl 4,4-ethylenedioxypentanoate reacts with aldehydes and ketones, and gives the expected β-hydroxyacids.The β-ethylenic ketones are isolated when the condensation is carried out
