Aryl ring migration reaction in the synthesis of 2,4-diaryl-4H-3,1- benzothiazines

A new rearrangement of 1-(diarylmethyl)-2-isothiocyanatobenzenes into 2,4-diaryl-4H-3,1-benzothiazine derivatives is described. Treatment of the starting compounds with aluminum trichloride under Friedel-Crafts conditions leads to migration of an aryl sub

Synthesis of cyclic iodonium salts containing an asymmetric carbon atom

We report the synthesis of two iodonium salts with an asymmetric carbon atom in the cation, viz. 3-methyl-10H,10-(4-tolyl)dibenz[b,e]iodinium tetrafluoroborate and the salt of the same cation with the anion of (-)-mono(N-α-phenylethyl)maleic acid amide as well as the synthesis of 3-methyl-10H-dibenz[b,e]-iodinium tetrafluoroborate. 1999 KluwerAcademic/Plenum Publishers.

Mass Spectral and Pyrolitic Studies of Some 4,4-Disubstituted 1,4-Dihydro-2H-3,1-benzoxazin-2-ones

Pyrolysis of 4,4-diaryl-1,4-dihydro-2H-3,1-benzoxazin-2-ones at 230-240 deg C gives 9-arylacridines and (2-aminophenyl)diarylmethanes.Their formation correlates well with the mass fragmentation of the respective parent compounds.

Intramolecular Nitrene Insertions into Aromatic and Heteroaromatic Systems. Part 7. Insertions into Electron-deficient Rings

A number of routes to o-aminotriphenylmethanes are described, where one benzene ring, or both, carry potential ester groups.The most useful synthon is shown to be the 1,3-dioxan-2-yl substituent, and using this methyl 2-aminodiphenylmethane-4'-carboxylate (18) and dimethyl 2-aminotriphenylmethane-4',4''-dicarboxylate (28) have been prepared.The azides from these, respectively (19) and (29), on thermolysis at 200 deg C gave azepinoindoles (48) and (51), the first examples of ring expansion by an arylnitrene of benzene rings with electron-withdrawing substituents.Also reported are syntheses of 3- and 4-(2-azidobenzyl)pyridines (38) and (39), and of 2-(2-azidobenzyl)thiazole (40); decomposition of these azides gave mainly polymers.
