Autor: Chao Xu, Yingkun Luo, Shengtong Niu, Fan Gong, Shouang Lan, Benlong Luo, Jinggong Liu, Shuang Yang, Xinqiang Fang

Publikováno v: Green Synthesis and Catalysis, Vol 5, Iss 4, Pp 303-309 (2024)

Ethers are among the most important chemicals in organic synthesis, the pharmaceutical industry, agrochemical production, and material science. C–O bond formation via substitution is one of the most widely used strategies for ether formation. Howev

Organocatalyzed trifunctionalization of alkynyl 1,2-diones for the concise synthesis of acyloxy allylidene malonates and γ-alkylidenebutenolides

Autor: Li Chen, Shengtong Niu, Shouang Lan, Wenjun Liu, Shuang Yang, Xinqiang Fang

Publikováno v: Green Chemistry. 24:3623-3628

Two unprecedented reactions using alkynyl 1,2-diketones and 1,3-dicarbonyls under phosphine catalysis have been achieved, furnishing a range of acyloxy allylidene malonates and γ-alkylidenebutenolides in good yields with high stereoselectivities.

Access to enantioenriched molecules with diverse fluorinated tetrasubstituted stereocenters using hydroxy as a kinetic resolution auxiliary group

Autor: Syeda Tazeen Zehra, Shouang Lan, Hao Zhang, Jinggong Liu, Shuang Yang, Xinqiang Fang

Publikováno v: Organic Chemistry Frontiers. 9:1040-1047

We describe in this paper that using secondary OH as the kinetic resolution auxiliary group, a series of previously unavailable fluorinated fully-substituted carbon molecules can be obtained with excellent level of enantioselectivities.

Autor: Ting Chen, Wenjun Liu, Wei Gu, Shengtong Niu, Shouang Lan, Zhifei Zhao, Fan Gong, Jinggong Liu, Shuang Yang, Andrej Emanuel Cotman, Jinshuai Song, Xinqiang Fang

Publikováno v: Journal of the American Chemical Society, str. 585-599 : Ilustr., Vol. 145, iss. 1, 2023
COBISS-ID: 512805913

Developing innovative dynamic kinetic resolution (DKR) modes and achieving the highly regio- and enantioselective semihydrogenation of unsymmetrical α-diketones are two formidable challenges in the field of contemporary asymmetric (transfer) hydroge
