[reaction: see text] A new approach for the synthesis of (+/-)-indatraline, which is a 3-phenyl-1-indanamine that displays several biological activities, is described. The strategy features as the key step a diastereoselective ring contraction of a 1,2-dihydronaphthalene promoted by PhI(OTs)OH, to construct the indan ring system. The oxidative rearrangement of other 1,2-dihydronaphthalenes was also investigated

A single-stranded antisense oligonucleotide, or a pharmaceutically acceptable salt thereof, capable of modulating expression and/or function of RPS25 gene, wherein nucleotides of the single-stranded antisense oligonucleotide are bonded to each other via a phosphate group and/or a modified phosphate group, the single-stranded antisense oligonucleotide includes a gap region, a 3′ wing region bonded to a 3′ end of the gap region, and a 5′ wing region bonded to a 5′ end of the gap region, the gap region is a deoxyribose-based nucleic acid optionally including a nucleic acid having a modified sugar moiety, each of the 3′ wing region and the 5′ wing region is a modified nucleotide, the single-stranded antisense oligonucleotide has a base length of 12- to 30-mer, and a base sequence of the antisense oligonucleotide is: a base sequence with a sequence identity of 90% to 100% to a base sequence complementary to at least one target region of the same base length as the antisense oligonucleotide present in the base sequence as set forth in SEQ ID NO: 1 or SEQ ID NO: 2; a base sequence complementary to a base sequence of the target region with deletion, substitution, insertion, or addition of one or several bases; or a base sequence capable of hybridizing under stringent conditions with an oligonucleotide having the target region.

of the indatraline enantiomers. This CSA was also tested for its ideal molar ratio, temperature, and solvent. Optimized conditions could be achieved that made determination of enantiopurity for (1R,3S)‐indatraline up to 98.9% enantiomeric excess (ee) possible. To quantify even higher enantiopurities, a high‐performanceliquid chromatography (HPLC) method based on a modified β‐cyclodextrine phase was
