Stereochemistry of the adduct from t-butylcyanoketen and 2-methylbut-2-ene; X-ray crystal and molecular structure of 2-cyano-3,3,4-trimethyl-2-t-butylcyclobutyl p-chlorobenzoate
Abstract
Cycloaddition of t-butylcyanoketen and 2-methylbut-2-ene proceeds regio- and stereo-specifically to give the cyclobutanone (1) whose structure is deduced by X-ray crystallography of the 4-chlorobenzoate of the derived alcohol (2).
