Abstract

Photochromic terarylene derivative 4 which has a sulfone group at the upper benzothiophene ring is readily synthesized using Suzuki coupling reaction. It exhibits good photochromic properties. Interestingly, the closed form of the compound 4 shows a good photostability as well as a thermal stability compared with its reduced analog 3, that provides a method to enhance the photostability of versatile photochromic terarylenes under UV.

For example, benzothiophene-bridged system 151 was prepared according to Scheme 47 from 2,3-dibromobenzothiophene and 3-methyl-2-thienylmagneisum bromide in 23% yield (08OL3639). Bis-sulfone 152 prepared from this photochrome does not exhibit photochromic properties, whereas its benzothiophene analog 153 is a typical photochrome (09TL5288), such as dihetarylethenes 154 and 155. A new class of photochromic diarylethenes containing thieno[3,2-b]thiophenes, dithieno[3,2-b:2′,3′-d]thiophene (08CC5203), and dithieno[3,2-b:2′,3′-d]pyrroles (09CEJ10005) with photoswitchable luminescence properties were synthesized by Suzuki cross-coupling reactions (Scheme 48).
This chapter focuses on the methods that are used for the synthesis of photochromic dihetarylethenes, in which both heterocycles are in vicinal positions at the double bond of cyclopentene, perfluorocyclopentene, and various heterocyclic moieties. The photocyclization of stilbenes and dihetarylethenes (DHEs) is accompanied by cis–trans isomerization, and the trans isomers do not give a cyclized form. Thus, products with a fixed cis conformation, in which the thienyl or benzothienyl moieties are linked to the double bonds of perfluorocyclopentene, maleic anhydride, and maleimide, are synthesized. Photochromes containing such “bridges” possess not only thermal irreversibility but also high fatigue resistance, amounting in some cases, to 10,000 cycles. These properties combined with other useful physicochemical characteristics offer ample opportunities for the use of dihetarylethenes in nonlinear optics, optical memory devices, as photoswitches, linkers, display elements, etc. Some dihetarylethenes, such as bis(indolyl)furan-2,5-diones that were covered by patents as typical photochromes have a broad spectrum of biological activities. This chapter discusses the synthesis of perfluorocyclopentene-bridged dihetarylethenes, dithienylperhydrocyclopentenes, and their heteroanalogs, synthesis of dithienyl photochromes containing a maleic anhydride fragment as the ethene-bridge and diarylmaleimides containing optically active dihetarylethenes.

However, if a strong electron-attracting group, such as cyano, carboxylate, etc., is introduced at the 5-position, the diazotization/iodination reaction sequence can occur thus facilitating Ullmann homo-coupling and Sonogashira cross-coupling reactions. Suzuki coupling reaction has also been used to prepare terarylenes by the coupling of dibutyl(2-methyl-benzo[b]thiophen-3-yl)borane with 2,3-dibromothiophene derivatives <09TL5288>. Functionalized benzothiophenes 78 were synthesized by a twofold Heck reaction with 76 that yielded diene 77 <09TL4962>.
This chapter presents the synthetic aspects of five-membered ring systems, particularly of thiophene and selenium/tellurium chemistry. Many of the preparations of thiopene rings give multi-substituted thiophene analogs. For example, a novel Cu(1)-catalyzed tandem addition/cycloisomerization reaction of sulfonylalkylidenethiiranes with terminal alkynes gives trifunctionalized thiophenes. Benzothiophene-based palladacycles that are resistance to air and moisture are made by a unique intramolecular thiopalladation of thioanisole substituted propargyl imines. 3-amino-5-chlorobenzo[b]thiophene-2-carboxylate that is prepared by the condensation of fluorobenzonitrile with methyl 2-mercaptoacetate reacts with formamide to give the 2-chloroacetimidoyl derivative, which is a lead compound in the synthesis of 3H-benzo[4,5]thieno[3,2-d]pyrimidin-4-ones. Several methods for constructing fused thiophenes is described in the chapter. Crossed-coupling reactions are extensively used in the elaboration of thiophene rings. The new cross-coupling reactions that have been developed eliminate the use of organic metallic derivatives and are, thus, more economically and environmentally attractive than traditional cross-coupling procedures that involve organometallic derivatives.
