Formal total synthesis of (±)-strictamine - the [2,3]-Stevens rearrangement for construction of octahydro-2H-2,8-methanoquinolizines.
For decades, akuammiline alkaloids have attracted synthetic chemists due to their intriguing molecular architecture. Among the different structural elements embedded in their carboskeleton, the methanoquinolizidine system constitutes the signature structural element of this alkaloid family. Herein, we describe a novel synthetic access to this system which relies on a [2,3]-Stevens rearrangement...
متن کاملSynthesis of 1,2,3,4,5,6,7,8-Octahydro-9-Ethoxy-10-Hydroxy-1-Anthracenone[OEHA]
Anthralin and some of its derivatives have implied antipsoriatic effect in clinical and pharmaceutical studies. Anthralin is synthesized by different strategies. In this work we report the synthesis of "OEHA" as a precursor of another biological active compound.
متن کاملA NOVEL QUINONE DIMETHIDE FORMED BY AERIAL OXIDATION OF 1,2,3,4,5,6,7,8- OCTAHYDRO-9,lO-DIHYDROXY1,-5 ANTHRACENEDIONE
During the development of a new regiospecific synthetic methodology for 1,5 dihydroxy- 9,lO-anthraquinone, it was observed that (anthrufin) preparative TLC of 1,2,3,4,5,6,7,8-octahydro-9,lO-dihyd roxy- 1,5-anthracenedione on silica gel produced a well-defined 1:l complex of the dione and an aerial oxidation product of it, the quinone dimethide 1,2,3,4,5,6,7- hexahydro-9,lO-dihydroxy-1 ,5-...
متن کاملSynthesis of Cis-Diammine (1,1-cyclobutane dicarboxylate) Platinum(II)
Platinum-based anticancer drugs are chemotherapeutic agents to treat cancer. Carboplatin (cis diammine cyclobutane dicarboxylate platinum (II)) is a second generation drug that has less toxic than cisplatin, allowing for high dosages. In the first stage, 1,3-Cyclobutane dicarboxylic acid, a key intermediate for the preparation of carboplatin, have been synthesized in good yields using diffe...
متن کاملEnergetics of intermolecular HONO formation in condensed-phase octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX)
We present preliminary work on the formation of HONO in condensed-phase HMX for the three pure polymorphic phases. Our results show that the energetics of the intermolecular hydrogen transfer (to form HONO on an adjacent molecule) is more favorable in d-HMX than in a-HMX and b-HMX. The energetics of this intermolecular hydrogen transfer process follow the same trends of HMX sensitivity, where d...
