Article abstract of DOI:10.1021/jo01302a004

The chiral hydrocarbon butylethylmethylpropylmethane (10) has been prepared in a state of known and high optical purity via two independent routes.The first synthesis has as its main feature the addition of 2-thienylmagnesium bromide to the α,β-unsaturate
