Abstract:
The oximes of 2-acylthioanisole derivatives may be conveniently converted into 1,2-benzisothiazoles by acetic anhydride in pyridine. 3-(2-Methylthiophenyl)-1,2-benzisothiazole, prepared by this method, has been further converted into the 1,2-benzisothiazolo[2,3-b]-1,2-benzisothiazolium system. The phenylhydrazones of certain 2-acylthioanisoles are also cyclized by polyphosphoric acid to 2-(2-methylthio)phenylindoles, which are further converted into benzo[b]thieno[3,2-b]indoles by demethylation and oxidation.

Abstract:
The treatment of di(2-amino-5-methylphenyl)methane with N-sulfinylmethanesulfonamide gives two materials, 3-(2-amino-5-methylphenyl)-5-methyl-2,1-benzisothiazole and what appears to be its tautomer, a 2,1-benzisothiazolo[2,3-b]-2,1-benzisothiazole derivative. Reaction of the former with methyl iodide gives mono-, di-, and trimethyl derivatives. The second of these also possesses the symmetrical 2,1-benzisothiazolo[2,3-b]-2,1-benztsothiazole structure. The structure of the other methylation product and of the acetylation products are discussed. Some 1,2-dithiol-3-ylidene-2-pyridylmethanes were

AbstractThe crystal structures of 2-isopropyl-benzisothiazol-3-one-7-carboxylicacid isopropyl amide and of the corresponding selenium and tellurium derivatives have been determined. In contrast to the sulfur and selenium compounds, the tellurium derivative has an unprecedented three-dimensional network structure held together via π-π stacking and hydrogen bonding interactions. The cavities in the 3D molecular network are filled with guestwater molecules that are hydrogen bonded to carbonyl oxygen atoms.

It explores the scope of natural products that are known within these families and discusses what they are used for, how they have been made and how they may have been biosynthesised. Chapter 1 provides a review of each family of natural products in turn. Chapter 2 describes the total synthesis of the benzisothiazole natural products aulosirazole and pronqodine A, and a series of unnatural analogues. The Chapter begins with a short discussion on the use of the Diels-Alder reaction for the formation of naphth
