Copper-Catalyzed, N-Directed Csp3–H Trifluoromethylthiolation (−SCF3) and Trifluoromethylselenation (−SeCF3)
摘要:
A direct and versatile copper-catalyzed trifluoromethylthiolation and trifluoromethylselenation of primary, secondary, and tertiary aliphatic C-H bonds was developed. The reaction provides direct access to molecules containing these emerging moieties in the presence of a wide range of common functional groups and in complex molecular environments.

Photoremovable NPEC group compatible with Ns protecting group in polyamine synthesis
Herein, we disclose an efficient combination of NPEC and Ns protectinggroups in the synthesis of polyamine, by showing the orthogonal reactivity using N-NPEC-N-Ns alkylamines prepared from NPEC-NHNs. Selective photodeprotection of NPEC group in 12-mer polyamine and the complex conjugate has been further demonstrated toward the synthesis of novel polyamine natural product protoaculeine B.
