Catalytic Ketyl-Olefin Cyclizations Enabled by Proton
2019-12-12 · Concerted proton-coupled electron transfer is a key mechanism of substrate activation in biological redox catalysis. However, its applications in organic synthesis remain largely unexplored. Herein, we report the development of a new catalytic protocol for ketyl-olefin coupling and present evidence to support concerted proton-coupled electron transfer being the operative mechanism of …

Ketal - an overview ScienceDirect Topics
Ketal (23) consists of two stereoisomers.X-ray crystallography and 1 H NMR data indicate a twist–boat chair conformation is thermodynamically favored over the twist–boat. The energies of activation for the interconversion were estimated to be 26.6 kcal mol −1 (twist–boat chair to twist–boat conformation) and 25.2 kcal mol −1 (twist–boat to twist–boat chair conformation) at 25

A ketal is a compound that has the following general structural formula.. R 1 = alkyl, aryl R 2 = alkyl, aryl R 3, R 4 = alkyl (In most ketals, R 3 = R 4; cyclic ketals are an exception.). eg: The functional group 1 in an organic molecule is called the ketal group; the carbon atom bearing the two oxygen atoms is the ketal carbon.. see also cyclic ketal
