A Straightforward Synthesis of 1,2-Dihydronaphtho[2,1-b]furans from 2-Naphthols. -The following mechanism for the furan synthesis is discussed: Michael-type addition of a naphthalenolates (I) to acrylates is followed -after aromatization and formation of the 2-naphthalenolate anion -by an intramole
2,3-Dihydronaphtho[l,2-b]thiophene 1-oxides, obtained by thermolysis of alkyl lnaphthyl sulfoxides, are reduced by lithium aluminum hydride to 2,3-dihydronaphtho[l,2-b]thiophenes, whereas under the influence of acetic and trifluoroacetic anhydrides they form naphtho[l,2-b]thiophenes. Compounds of th
