dienamides is described which relies upon the acid-catalyzed or therma ynamine-CZaisen rearrangement with readiZy accessible laryZthiolynamines. The Claisen rearrangement has found substantial utility in the methodology of synthetic organic chemistry.2) For example, the reaction of an allylic alcoho

Reaction of pyran-2-thiones 4 with nitroso derivatives led surprisingly to type-8 (19) adducts which proved to be isomeric with the initially expected primary Diels-Alder cycloadducts 5. Methyl 2-thioxo-2H-pyran-5-carboxylate (40, when reacted with nitrosobenzene at -lo", led quantitatively to the t
## Abstract The reaction of 3,4โdihydroisoquinolinium salt 11 with phenylโN,Nโdimethylaminoacetylene 12 affords the (1:2)โadduct, the dihydrobenzo(d)azecinium salt derivative 13. The structure assignment is based on a preliminary Xโray analysis as well as on analytical and spectral data. It is assu
