01 Jan 1985-Journal of The Chemical Society, Chemical Communications (The Royal Society of Chemistry)-Vol. 9, Iss: 9, pp 533-534
TL;DR: In this paper, a combination of a Diels-Alder reaction with a [3,3] sigmatropic shift was used to produce the rearranged products of type 6.
Abstract: 1-Thiocyanatobuta-1,3-dienes react with strong dienophiles to produce directly the rearranged products of type (6)via a combination of a Diels–Alder reaction with a [3,3] sigmatropic shift.

TL;DR: In this article, the authors present die Regioselektivitat bei Verwendung nicht-symmetrischer Reaktionspartner sowie die Instabilitat vieler potentieller 2π-and 4π-Systeme.
Abstract: Wenn auch im vorangegangenen Kapitel der Eindruck entstanden sein mag, das alle Stolpersteine der Dien-Synthese aus dem Wege geraumt seien, so mus doch leider jetzt erkannt werden, das gegen die beiden hartnackigen Argernisse der intermolekularen Cycloadditionsreaktionen trotz aller Fortschritte und Tricks doch noch so recht kein Kraut gewachsen ist. Es sind dies die Regioselektivitat bei Verwendung nicht-symmetrischer Reaktionspartner sowie die Instabilitat vieler potentieller 2π- und 4π-Systeme.
