Ai-Lan Lee of Heriot-Watt University developed a protocol for the decarboxylation of the carboxylic acid 1 to the hydride 2 (Org. Lett. 2022, 24, 686. DOI: 10.1021/acs.orglett.1c04079). Joseph R. Clark…
Histology of proximal tibia showed important decreases in MS/BS, MAR and BFR/BS in the OVX rats compared with the sham, plus the CFE group totally maintained these parameters for the…
Lbeit to a lesser extent than with phenformin, and DHAP and glyceraldehyde3phosphate are slightly decreased. Neither biguanide has an impact around the earliest glycolytic intermediates that are elevated during transformation…
Jin-Na Song of Jilin University and Yongquan Ning of Northeast Normal University assembled the furan 3 by combining the diazoalkane derived in situ from the tosylhydrazone 2 with the β-keto…
Pher G. Andersson of Stockholm University showed that a Z/E mixture of the enone 1 could be hydrogenated to 2 in high ee (Nature Commun. 2022, 13, 361. DOI: 10.1038/s41467-022-28003-6).…
Stefan Schulz of the Technische Universität Braunschweig updated the classic intramolecular Diels-Alder cycloaddition of the triene 1 to the ketone 2, readily convertible to δ-cadinol (3), by preparing 1 via…
Liang-Nian He of Nankai University and Chao-Jun Li of McGill University converted the hydrazone of carvone 1 to the triene 2 (JACS Au 2022, 2, 1929. DOI: 10.1021/jacsau.2c00320). Mathias Schelwies…
Efficient new methods for oxidation are always welcome. The Dess-Martin periodinane has become the workhorse for alcohol to aldehyde or ketone conversion in organic research labs around the world. 5-Azaspirooctane-6,8-dione…
Xufeng Lin of Zhejiang University used an enantiomerically-pure bis iodide to mediate the oxidative cyclization of the prochiral amine 1 to the lactam 2 (Tetrahedron Lett. 2022, 109, 154157. DOI:…
