Friedel–Crafts-type reaction of pyrene with diethyl 1-(isothiocyanato)alkylphosphonates. Efficient synthesis of highly fluorescent diethyl 1-(pyrene-1-carboxamido)alkylphosphonates and 1-(pyrene-1-carboxamido)methylphosphonic acid
Friedel-Crafts-type reaction of pyrene with diethyl 1-(isothiocyanato)alkylphosphonates promoted by trifluoromethanosulfonic acid afforded diethyl 1-(pyrene-1-carbothioamido)alkylphosphonates in 83-94% yield. These compounds were transformed, in 87-94% yield, into the corresponding diethyl 1-(pyrene-1-carboxamido)alkylphosphonates by treatment with Oxone(®). 1-(Pyrene-1-carboxamido)methylphosph...
متن کامل1-(Hydroxymethyl)pyrene
The asymmetric unit of the title compound, C(17)H(12)O, contains two molecules, in which the fused aromatic ring systems are almost planar [maximum deviations = 0.0529 (9) and 0.0256 (9) Å]. In the crystal, aromatic π-π stacking inter-actions (perpendicular distance of centroids of about 3.4 Å) and strong O-H⋯O hydrogen bonds result in a helical arrangement of pyrenyl dimers.
متن کاملHalonium-initiated electrophilic cascades of 1-alkenoylcyclopropane carboxamides: efficient access to dihydrofuropyridinones and 3(2H)-furanones.
Halonium-initiated cascade reaction of 1-alkenoylcyclopropane carboxamides was developed, which leads to the production of dihydrofuropyridinones and 3(2H)-furanones, respectively, depending on the property of substituents on the enone moiety.
متن کاملA convenient synthesis of 1-benzhydryl-N-arylsulfonyl-3-oxo-1,2-diazetidine-2-carboxamides.
In a search for novel compounds possessing potent antibiotic activity, a synthetic program was initiated aimed at the preparation of 1,2diazetidin-3-ones (monocyclic aza-p-lactams). The pioneering work of TAYLOR and coworkers1,2) provided a paradigm for this study as well as facile entry into this fascinating class of compounds. One aspect of the present study focused on the incorporation of an...
متن کامل1-[(5-Bromopentyloxy)methyl]pyrene
In the title compound, C(22)H(21)BrO, other than the Br atom, the non-H atoms are approximately co-planar [maxium deviation = 0.178 (2) Å] and the alk-oxy chain shows an all-anti conformation. A weak inter-molecular C-H⋯Br hydrogen bond contributes to the stabilization of the crystal structure.
