Selective Aerobic Oxygenation of Tertiary Allylic Alcohols with Molecular Oxygen

Abstract

Aerobic epoxidation of tertiary allylic alcohols remains as ignificant challenge.R eported here is an efficient and highly chemoselective copper-catalyzed epoxidation and semipinacol rearrangement reaction of tertiary allylic alcohols with molecular oxygen. The solvent 1,4-dioxane activates dioxygen, therebyp recluding the addition of as acrificial reductant.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Metal-free synthesis of N-sulfonylformamidines via skeletal reconstruction of sulfonyl oximonitriles

“…10 Among the various types of sulfonyl oxime ethers, sulfonyl oximonitrile is a promising specimen, which has been widely used in organic synthesis. 11 For instance, in 2009, Carreira et al developed an efficient Co-catalyzed reductive coupling of unactivated alkenes with sulfonyl oximonitriles. 12 In 2016, Jiao et al described an expedient silver-catalyzed radical transformation of aliphatic carboxylic acids to access diverse oxime ethers in good yields.…”
