Two possible routes have been investigated for the synthesis of 1-heterocycloheptatrienes starting from annulated cyclobutene derivatives. The first approach comprised a [2 + 2 + 2] cycloreversion of tetracyclic compounds prepared from 2,3-bis(methox

A 1-benzoxepin has been synthesized in high yield by cycloaddition of 3-pyrrolidinobenzofuran to dimethyl acetylenedicarboxylate, followed by thermal rearrangement of the [2 + 2] cyclo-adduct. A kinetic study of the isomerization revealed that the ri

A general method has been developed for the synthesis of two novel classes of heterocyclic compounds, 2,3-(or 2,7)-dihydrothiepins and 2,3-dihydro-8H-thiocins. It comprises the cycloaddition of enamine derivatives of tetrahydro-thiophen-3-ones or 4-t

A number of non-ionic compounds have been found to form solid complexes with 18-crown-6. The highest efficiencies of isolation and the highest selectivities were obtained with nitromethane, dimethyl carbonate and dimethyl oxalate. The usefulness of t

The enamine-like character of a pyrrolidino-substituted carbon-carbon double bond in heteroaromatics has been demonstrated by the fact that such compounds can undergo cycloaddition reactions with 1,3-dipolar reagents such as benzonitrile oxides, diar

Ketenes react with 1-pyrrolidinyl-substituted heteroaromatics 3-5 to give 2-acyl derivatives 10, 13, 16-18 and 20 and, in some cases 2: 1 reaction products 11 and 12. The latter products can be attributed to reaction of 1,4-dipolar intermediates with
