Succinic anhydride and behenic acid have been used to attach C4 and C22 carbon chains on to 2 and 5 positions of thiophene through two alternate acylation sequences.Raney nickel desulphurization to the 2,5-disubstituted thiophene yielded triacontanoic acid esters which on LAH reduction gave 1-triacontanol.

A visible light-driven, copper-catalyzed aerobic oxidative cleavage of cycloalkanones has been presented. A variety of cycloalkanones with varying ring sizes and various α-substituents reacted well to give the distal keto acids or dicarboxylic acids with moderate to good yields.
Novel synthetic method for duloxetine intermediate

Paragraph 0008; 0017, (2018/09/08)
The invention provides a novel synthetic method for a duloxetine intermediate (S)-N-methyl-3-hydroxy-3-(2-thienyl)-1-propylamine (a compound 1 as described in the specification). According to the method, thiophene and succinic anhydride are used as raw materials and undergo Friedel-Crafts acylation, esterification, aminolysis, asymmetric hydrogenation, and oxidative degradation so as to obtain theduloxetine intermediate (the compound 1).
