Summary: Introducing a small phosphorus-based fragment into molecules via trapping and releasing reactive phosphorus-based molecules is an important process in synthetic chemistry. This study used electron-rich hexaphenylcarbodiphosphorane to stabilize the least thermodynamically favorable isomer of HO2P and transfer it to various substrates. Additionally, several phosphorus-based compounds were isolated and characterized using this synthetic approach.

Summary: The behavior of several base-stabilized silyliumylidene ions with different ligands was found to be strongly influenced by the nature of the ligand. Among them, the silylene- and sulfide-supported complexes exhibited higher reactivity and were capable of sequentially activating multiple small molecules. Of particular interest, the silylene-supported silyliumylidene complex was able to activate two H2 molecules.

Summary: This study reports kinetically controlled supramolecular polymerization of boron-containing p-conjugated molecules using a seeding method based on dual trapping of a metastable state. The formation of helical supramolecular nanostructures with intense J-type aggregate emission was achieved through cooperative supramolecular polymerization. The presence of a Lewis acid-base complex enhanced the stabilization of the metastable monomeric state, allowing for successful production of homogeneous nanofibers even at high concentrations.

Summary: This study isolated two previously unreported furanosesquiterpenes and three unprecedented gamma-lactone-containing analogues from three Myoporum species. Additionally, nine previously reported furanosesquiterpenes and five other natural products were also isolated. Three distinct types of furanosesquiterpene structures were observed in each of these Myoporum species. Four sesquiterpene natural products, including the lactam-containing sesquiterpene myoporumine A, were synthesized from (-)-ngaione in two steps for each case.

Summary: This study presents a gold-catalyzed bis[(trifluoromethyl)sulfonyl]ethylation of alpha-allenols, allowing the synthesis of sterically congested bis(triflyl)enals with quaternary carbon centers. The reaction pathway is different from the conventional approach, as Au(I) acts as a pi-Lewis base catalyst instead of a pi-Lewis acid, activating the allene and facilitating the unusual addition of a carbon nucleophile from the gold complex belonging to the allenol moiety. Density functional theory calculations were performed to understand this unique pathway.

Summary: The aluminum analogue of Piers' borane, [HAl(C6F5)(2)](3)1, was prepared on a gram-scale. DFT calculations showed that 1 has a higher fluoride ion affinity (FIA) than Piers' borane, and the Al-H moiety proved to be a strong hydride donor, reacting with alcohol and terminal alkyne to give dehydrogenative products 3 and 4. Hydroalumination product 5 was obtained via the reaction of 1 with aldehyde. Additionally, 1 catalyzes the hydrosilylation of alkynes and alkenes.

Summary: The combination of alkoxyphosphoranes and borane generates zwitterions that act as FLP and can alkylate nucleophiles to form C-C, C-N, C-H, and C-Cl coupling products. A DFT study reveals that the reaction proceeds through an FLP activation pathway, forming an alkoxyphosphonium intermediate that facilitates the alkylation of nucleophiles, similar to the Mitsunobu reaction.

Summary: The reactivity of the free aluminylene [N]-Al (1) towards boron Lewis acids was studied. A rare example of the free alumaborane [N]-Al(BPh2)(OBPh2) (2) with an Al-B electron-sharing bond was formed by oxidative addition of 1 with Ph2BOBPh2. On the other hand, complexation of 1 with B(C6F5)(3) and HB(C6F5)(2) resulted in the corresponding Lewis adducts [N]-Al -> B(C6F5)(3) (3) and [N]-Al -> BH(C6F5)(2) (4) with an Al -> B dative bond. Crystallization of 4 in Et2O produced the adduct [N]-Al(Et2O)-> BH(C6F5)(2) (5). Quantum chemical calculations were performed to understand the formation of 2 and the bonding situation of 3 and 5.

Summary: We discovered a tris(carbene)borate (TCB) ligand that can stabilize an unprecedented nucleophilic Sn(II) cation salt. The strong electron-donating ability of [PhB-(tBuIm)3]- makes the cationic tin atom electron-rich, sigma-donating, and slightly pi-accepting, allowing for easy oxidation with o-chloranil and S8, as well as coordination with coinage metals. Quantum chemical computations were used to probe the electronic structures of these species. These findings reveal an additional role for TCB ligands in isolating unprecedented p-block species.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
