[2.2] Paracyclophane-1,9-dienes substituted with n-octyl chains have been synthesised from the corresponding dithia[3.3] paracyclophanes using a benzyne induced Stevens rearrangement. The use of 2-(tri-methylsilyl) phenyl trifluoromethanesulfonate and tetra-n-butylammonium fluoride as the in situ benzyne source gave significantly improved yields over traditional sources of benzyne and enabled the preparation of n-octyl substituted [2.2] paracyclophane-1,9-dienes on a multi-gram scale.

Synthesis of the polymers containing norbornene and tetraphenylethene by ring-opening metathesis polymerization and their structural characterization, aggregation-induced emission and aniline detection

Chia-Jung Lin, Yi-Hao Lin, Tai-Chin Chiang, Chin-Yang Yu

Summary: Well-defined norbornene-based homopolymers and block copolymers with low polydispersity index and close to theoretical molecular weight were synthesized using the third-generation Grubbs' initiator. These polymers exhibit aggregation-induced emission characteristics and high emission in solid and aggregate states. They show strong sensing ability for aniline in the aggregated state with a detection limit of 5 x 10-6 M.

Synthesis of poly(lactide-co-glycolide) containing high glycolide contents by ring-opening polymerization as well as their structural characterizations, thermal properties, morphologies, and hydrophilicity

Van Hoang-Khang Phan, Yi-Hsin Tai, Tai-Chin Chiang, Chin-Yang Yu

Summary: This article focuses on the synthesis and properties of random copolymers poly(l-lactide-r-glycolide) and block copolymers poly(l-lactide-b-glycolide). The results show that block copolymers have better thermal stability and crystallinity compared to random copolymers, and also exhibit higher hydrophilicity.

Catalyst-free photo-induced aerobic radical synthesis of lactams from N-alkenyl trichloroacetamides in 2-methyltetrahydrofuran as the radical initiator under violet light

Faiza Diaba, Gisela Trenchs

Summary: The first violet light-mediated synthesis of gamma- and delta-lactams from N-alkenyl trichloroacetamides is reported in this paper. The reactions are conducted in tetrahydrofuran or 2-methyltetrahydrofuran as the sole solvent without catalysts or additives, under non-anhydrous conditions in an air atmosphere where the solvent serves as the radical initiator.

Catalyst-free assembly of a polyfunctionalized 1,2,4-triazole-fused N-heterocycle, 6-acylated pyrrolo[1,2-a][1,2,4]triazolo[5,1-c]pyrazine

Hyunjin Oh, Ikyon Kim

Summary: A new 1,2,4-triazole-pyrrolo[1,2-a]pyrazine hybrid system, 6-acylpyrrolo[1,2-a][1,2,4]triazolo[5,1-c]pyrazine, was synthesized using a catalyst-free method. This method involved sequential exposure of pyrrole-2-carbonitrile-derived substrates to DMF-DMA and acyl hydrazide, resulting in the formation of acylated pyrazine and 1,2,4-triazole rings, enabling the installation of various substituents at specific positions on the core skeleton.

Microbial alcohol dehydrogenases: recent developments and applications in asymmetric synthesis

Anju Chadha, Santosh Kumar Padhi, Selvaraj Stella, Sowmyalakshmi Venkataraman, Thangavelu Saravanan

Summary: Alcohol dehydrogenases are enzymes that use cofactors for oxidation or reduction reactions of alcohols or carbonyl compounds. They are utilized in green chemistry and have applications in the production of pharmaceuticals. Recombinant enzymes have solved the challenge of producing purified enzymes in large quantities. Engineered alcohol dehydrogenases have been used in asymmetric synthesis in industry. Various methods have been established for regenerating expensive cofactors to make the enzymatic process more efficient and economically viable.
