Die Titelverbindung (I) reagiert als Dienophil mit den in Position 1 substituierten 1,3‐Butadienen (II) und mit den in Position 2 substituierten Butadienen (IV) in einer Diels‐Alder‐Reaktion zu den 1,2‐Thiazinoxiden (III) bzw. (V), die als o‐Addukte bzw. p‐Addukte klassifiziert werden.
Whereas with tBuOK in THF ring‐opening of the title compounds (I) exclusively leads to dehydrated products (III) (yield 90%), with NaOH compounds (Id), (Ie) yield (IId), (IIe) as well, and (If) exclusively leads to (IIf).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
