WebNov 7, 2024 · In the case of bishomoallylic alcohols, an intriguing ligand-induced divergent reactivity was observed. A terminal-to-internal alkene isomerization promoted by Rh/L7 followed by redox isomerization using Rh/BINAP system produced chiral ketones bearing a γ-stereocenter with high yield and enantioselectivity. Mechanistic studies … WebMar 20, 2024 · The quinoxalinonyl-functionalization of alkenes employs the quinoxalinone-substituted tertiary bishomoallylic alcohols as substrates, proceeds through …

WebNov 17, 2024 · Specially, for the reaction of allylic alcohols, another intramolecular pathway with the intermediacy of a metal-alkoxide species might occur, and more details will be discussed later in this perspective. ... Bishomoallylic alcohols could be transformed into γ-chiral ketones via a two-step sequence involving terminal-to-internal alkene ... WebAllylic and cis-homoallylic alcohols are epoxidized readily, but frans-homoallylic and bishomoallylic alcohols react slowly, if at all. The stereoselectivity in the epoxidation of acyclic allylic alcohols is the same as and is comparable to that observed with r … lithium cr2025 battery
