Kawanami, Yasuhiro,Katsuki, Tsutomu,Yamaguchi, Masaru
, p. 5131 - 5132 (1983)
In the presence of silver tetrafluoroborate, S-ethyl carbothioates reacted with 1-alkynyltrimethylsilanes to give the corresponding acetylenic ketones in good yields.
Alkynylation of aldehydic C-H bonds via reaction with acetylenic triflones.
Gong, Jianchun,Fuchs
, p. 787 - 790 (1997)
Reaction of aldehydes with acetylenic triflones affords acetylenic ketones and alkylated acetylenes via the intermediacy of acyl radicals, the product ratio being highly dependent upon aldehyde structure and reaction conditions.
Synthesis of substituted benzo[: B] [1,4]oxazepine derivatives by the reaction of 2-aminophenols with alkynones
Oshimoto, Kohei,Zhou, Biao,Tsuji, Hiroaki,Kawatsura, Motoi
, p. 415 - 419 (2020/01/30)
We have developed a novel synthetic method accessing benzo[b][1,4]oxazepines that are one of the rare classes of benzoxazepine derivatives by reaction of 2-aminophenols with alkynones in 1,4-dioxane at 100 °C. A series of benzo[b][1,4]oxazepine derivatives can be prepared by using this synthetic protocol. Mechanistic experiments indicated that the hydroxy proton of the aminophenol could play a crucial role in the formation of an alkynylketimine intermediate that undergoes 7-endo-dig cyclization.
Intramolecular and Ferrier Rearrangement Strategy for the Construction of C1-β-d-xylopyranosides: Synthesis, Mechanism and Biological Activity Study

A stereoselective synthesis of C1-β-d-xylopyranoside derivatives had been developed via intramolecular 1,3-acyloxy migration/Ferrier rearrangement stategy from readily available propargylic carboxylates and d-xylal. A combined catalytic system of chloro(t
