Journal ArticleDOI
Chemoselective synthesis of homoallylic fluorides from cyclopropylmethanols by ring opening
TL;DR: In this paper, cyclopropylmethanols with pyridinium poly(hydrogen fluoride) in chlorobenzene-diisopropylamine in the presence of KHF 2 gave selectively homoallylic fluorides.
Journal ArticleDOI
Selective bromofluorination of alkenes with 1,3-dibromo-5,5-dimethylhydantoin and silicon tetrafluoride
TL;DR: Alkenes have been converted into corresponding bromofluorides by reaction with 1,3-dibromo-5,5-dimethylhydantoin (DBH) and silicon tetrafluoride in 1,4-dioxane in a highly regio-, stereo-, and chemo-selective manner as mentioned in this paper.
Journal ArticleDOI
Trichoclin, a new furocoumarin from trichocline incana
TL;DR: The structure for trichoclin, (E )-8-(3-methyl-4-hydroxy-2-butenyloxy)-psoralen, a new furocoumarin isolated from Trichocline incana, has been established as discussed by the authors.

Facile Preparation of Tetrabutylphosphonium Fluoride and Its HF Adducts. New Fluoride Anion Sources for Selective Nucleophilic Fluorination
TL;DR: Anhydrous tetrabutylphosphonium hydrogen bifluoride (2), dihydrogen trifluride prepared from aq. tetrabilibrutyl-phosphoneium hydroxide (Aq. HF) and tetrabalabutyphosphonic acid (TPA) fluoride prepared from 2 and BunLi were shown to be useful fluoride sources for selective nucleophilic fluorination of oxiranes, alkyl halides, alcohols and sulfonates of aliphatic and steroidal species
