A convenient synthesis of thieno[3,2-b]indoles and thieno[3,4-b]indoles has been developed. The protocol involves a site-selective Suzuki reaction, followed by a double C–N coupling reaction using anilines, benzylamines, or alkylamines. The yields range from good to excellent.

Paragraph 0294, (2014/09/29)
A compound according to Formula IA and IB, reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer A and a ring-closed isomer B is provided. For substitutent groups, Z is N, O or S; each R1 is independently selected from the group consisting of H, or halo; each R2 is independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both R2 together form —CH═CH— and form part of a polymer backbone; each R3 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each R4 is aryl; and each R5 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl.
