Abstract

Conclusion Scheme 3 provides a straightforward synthesis for 1, 4-dienes with variable substitution pattern. This method may be considered as a variant of the Boord olefin synthesis (Scheme 5)"'), which has also been employed for the synthesis of 1, 4-dienes by using allylic Grignard reagents'! As unsymmetrical allylmagnesium halides often do not react regioselectively, the advantage of the method presented in this article is not only the ...
