Intercepting the Nazarov Oxyallyl Intermediate with α-Formyl-vinyl Anion Equivalents to Access Formal Morita-Baylis-Hillman Alkylation Products
Wu, Yen-Ku,Lin, Rongrong,West
, p. 1486 - 1490 (2017)
A Lewis acid catalyzed cationic domino reaction involving sequential electrocyclization and polar addition of allenol ethers onto the resulting oxyallyl species is described. The overall sequence allows a highly stereoselective synthesis of densely substituted cyclopentanoid compounds containing α-formylvinyl functionality which is formally equivalent to products of a Morita-Baylis-Hillman alkylation process.
2,2′-Biphenol/B(OH)3 catalyst system for Nazarov cyclization
Sugimoto, Kenji,Oshiro, Miyu,Hada, Ryuhei,Matsuya, Yuji
, p. 1019 - 1022 (2019/09/12)
A novel catalyst system—a combination of the readily available 2,2′-biphenol with the inexpensive, nontoxic, and eco-friendly B(OH)3—promoted the Nazarov cyclization of activated and inactivated divinyl ketones to afford the corresponding cyclo
Synthesis of cyclopentenols and cyclopentenones via nickel-catalyzed reductive cycloaddition
Jenkins, Aireal D.,Herath, Ananda,Song, Minsoo,Montgomery, John
supporting information; experimental part, p. 14460 - 14466 (2011/11/04)
Strategies for the reductive cycloaddition of enals or enoates with alkynes have been developed. The enal-alkyne cycloaddition directly affords cyclopentenols, whereas the enoate-alkyne cycloaddition affords the analogous cyclopentenones. The mechanism of
