Visible light photoredox catalyzed deprotection of 1,3-oxathiolanes

An efficient visible light photoredox catalyzed aerobic deprotection of 1,3-oxathiolanes using organic dye Eosin Y as a photocatalyst is disclosed. The deprotection procedure features the use of a metal-free catalyst, mild conditions, a broad range of substrate scope, and good functional group tolerance. 35 examples were tested under the standard conditions and most of them afforded the deprotected products in modest to high yields.

7-Substituted Benzothiophenes and 1,2-Benzisothiazoles. Part 2. Chloro and Nitro Derivatives

The 7-chloro and 7-nitro derivatives of benzothiophene and 1,2-benzisothiazole have been prepared from readily available precursors, which for each substituent are common to both ring systems. 7-Chlorobenzothiophene has been obtained from 3-chloro-2-mercaptobenzoic acid via 7-chlorobenzothiophen-3(2H)-one, or from 2,3-dichlorobenzaldehyde, either via β-(2,3-dichlorophenyl)-α-mercaptoacrylic acid (16) or, preferably, via 7-chlorobenzothiophene-2-carboxylic acid.Hexamethylphosphoric triamide is a particularly useful solvent in which to effect the selective nucleophilic replacement of the 2-chloro substituent in 2,3-dichlorobenzaldehyde. 7-Chloro-1,2-benzisothiazole is available by treatment of 3-chloro-2-mercaptobenzaldehyde with chloramine (57percent), or by heating 2,3-dichlorobenzaldehyde with sulphur and aqueous ammonia (46percent). 7-Nitrobenzothiophene has been obtained by treatment of 2-bromo-3-nitrobenzaldehyde with mercaptoacetic acid under alkaline conditions, followed by decarboxylation of the resulting 2-carboxylic acid.Cyclisation of 2-(n- or t-butylthio)-3-nitrobenzaldoxime with polyphosphoric acid gives 7-nitro-1,2-benzisothiazole in high yield. 3-Nitro-2-t-bytylthiobenzaldehyde behaves unexpectedly with chloramine, to give what is believed to be 7-nitro-2-t-butyl-1,2-benzothiazolium chloride (24) (73percent).
