Electrosynthetic C−O Bond Activation in Alcohols and Alcohol Derivatives
Angewandte Chemie, Volume 135, Issue 4, January 23, 2023., 2023 Deoxygenative transformations of alcohols and their derivatives are often challenging due to the thermodynamic penalty associated with the cleavage of the C−O bond. This Review includes preparative protocols and their mechanistic aspects for the activation and functionalization of C−O bonds, detailing direct and indirect electrosynthetic methods, as ...

Synthetic studies towards d-modified paclitaxel analogues [PDF]
Journal of the Serbian Chemical Society, 2012 A synthetic sequence has been developed for the preparation of 9,10-O-diacetyl-4-desmethylene-4β-(3-butenyl)-4α-hydroxy-5-O-mesyltaxicin I-1,2-carbonate 3, an intermediate in the attempted synthesis of cyclobutane paclitaxel analogue.

ChemElectroChem, Volume 10, Issue 22, November 14, 2023., 2023 Herein, electroreductive C−OH bond activation and subsequent deoxygenative C−H and C−C bond formation is demonstrated for non‐derivatized benzylic and propargylic alcohols. The cathodic transformations proceed via carbanions, formed via radical‐polar crossover, and are efficiently balanced by anodic oxidation of borohydride additives, a strategy that ...

Synthesis and Structure‐Activity Relationship Studies of C(13)‐Desmethylene‐(−)‐Zampanolide Analogs
Chemistry – A European Journal, Volume 29, Issue 36, June 27, 2023., 2023 Reduced or demethylated variants of a C(13)‐desmethylene congener of the marine microtubule stabilizer (−)‐zampanolide have been prepared by HWE‐based macrocyclization and stereoselective construction of the hemiaminal center in the side chain. While all modifications led to reduced growth inhibitory activity, the 2,3‐dihydro and the C(17)‐desmethyl ...
