Abstract
The ongoing COVID-19 global pandemic caused by SARS-CoV-2 inspires the development of effective inhibitors to block the SARS-CoV-2 spike-ACE2 interaction. A chemical investigation on the fruiting bodies of Phellinus pini led to the isolation of five aromatic cadinane sesquiterpenoids including four new ones, named piniterpenoids A-D (1-4), as well as three known lignans. Their structures were determined by extensive spectroscopic analysis including HRMS and 1D and 2D NMR. All of the aromatic cadinane sesquiterpenoids inhibited the SARS-CoV-2 spike-ACE2 interaction, with IC50 values ranging from 64.5 to 99.1 μM. A molecular docking study showed the disruption of the interaction of compound 1 via hydrogen interactions with Arg403, Asp405, and Arg408 of SARS-CoV-2 RBD and Arg393 and His34 residues of ACE2. These results suggested that aromatic cadinane sesquiterpenoids might be useful in developing agents for COVID-19.

Abstract
Cumin (Cuminum cyminum L.), a widely consumed food spice, has been reported to have antiglycative effects in vitro and in vivo, but there is a paucity of data on its bioactive compounds. Herein, we report the isolation and structure elucidation (by NMR, HRESIMS, and CD) of 21 (1-21) compounds from a methanol extract of cumin seeds. The isolates included five new compounds: two sesquiterpenoids, two pairs of monoterpeneoid epimers, and a chalcone, named cuminoids A-E, respectively. The isolates were evaluated for antiglycative effects using the bovine serum albumin-fructose intrinsic fluorescence assay. At equivalent concentrations, several of the isolates, including cuminoids C-E, were more potent inhibitors than the positive control, aminoguanidine, a synthetic antiglycative agent (>50 vs 35%, respectively).

Abstract
Epoxides are versatile intermediates in organic synthesis, but have rarely been employed in cross-coupling reactions. We report that bipyridine-ligated nickel can mediate the addition of functionalized aryl halides, a vinyl halide, and a vinyl triflate to epoxides under reducing conditions. For terminal epoxides, the regioselectivity of the reaction depends upon the cocatalyst employed. Iodide cocatalysis results in opening at the less hindered position via an iodohydrin intermediate. Titanocene cocatalysis results in opening at the more hindered position, presumably via Ti(III)-mediated radical generation. 1,2-Disubstituted epoxides are opened under both conditions to form predominantly the trans product.

Abstract
Biotransformations of the sesquiterpene ketone nootkatone from the crude drug Alpiniae Fructus and grapefruit oil, and the sesquiterpene hydrocarbon valencene from Valencia orange oil were carried out with microorganisms such as Aspergillus niger, Botryosphaeria dothidea, and Fusarium culmorum to afford structurally interesting metabolites. Their stereostructures were established by a combination of high-resolution NMR spectral and X-ray crystallographic analysis and chemical reaction. Metabolic pathways of compounds and by A. niger are proposed.

Abstract
[structure: see text] The work describes the enzyme-mediated preparation and the odor evaluation of the single stereoisomers of the commercial odorants Muguesia and Pamplefleur. The synthetic approach to Muguesia stereoisomers helped to clear the assignment of the relative configuration of intermediate diols 5. The odor response of Pamplefleur isomers was found to be rather unusual. No stereoisomer prevailed, but each one played a definite role in establishing the odor sensation of the final blend.

Abstract
Nootkatone, the most important and expensive aromatic of grapefruit, decreases the somatic fat ratio, and thus its demand is increasing in the cosmetic and fiber sectors. A sesquiterpene hydrocarbon, (+)-valencene, which is cheaply obtained from Valencia orange, was biotransformed by the green algae Chlorella species and fungi such as Mucor species, Botryosphaeria dothidea, and Botryodiplodia theobromae to afford nootkatone in high yield.

Abstract
A series of 3,5-dihydroxyheptenoic acid derivatives containing pyrazolopyridine, isoxazolopyridine, thienopyridine, and pyrazolopyrimidine as a key scaffold was synthesized from condensed pyridine and condensed pyrimidine carboxylic acid esters by homologation, aldol condensation with ethyl acetoacetate dianion, and stereoselective reduction of the 5-hydroxyketone. Several compounds in the series were found to have potent HMG-CoA reductase inhibitory activities in vitro and marked cholesterol biosynthesis inhibitory activities in vivo. It has been shown that these scaffolds can be used as a suitable replacement for the hexahydronaphthalene ring present in naturally occurring HMG-CoA reductase inhibitors.

Abstract
1. The enantioselective metabolism of cumene (isopropylbenzene) was studied in intact rabbits. 2. Of the total 2-phenyl-1-propanol formed metabolically, 90.3% was shown by h.p.l.c. to be (R)-(+)-2-phenyl-1-propanol. The corresponding values for (S)-(+)-2-phenylpropanoic acid and (R)-(-)-2-hydroxy-2-phenylpropanoic acid were 99.0 and 81.0%, respectively. 3. These results imply that firstly, preferential omega-hydroxylation occurs at the pro-S methyl group and secondly, the oxidation is followed by stereochemical inversion of (R)-(-)-2-phenylpropanol to the corresponding (S)-(+)-acid.
