	M791 Hamzeh Kiyani and Mahdi Ardyanian Short Note: N-(4-(6-(4-nitrophenyl)-4-phenyl-1,3-diazabicyclo[3.1.0]hex-3-ene-2-yl)phenyl)acetamide Molbank 2013, 2013(1), M791; doi:10.3390/M791 Received: 29 October 2012 / Accepted: 25 December 2012 / Published: 28 December 2012 Show/Hide Abstract | Download PDF Full-text (251 KB) |  Abstract: As a result of three-component one-pot reaction of trans-2-benzoyl-3-(4-nitrophenyl)aziridine with 4-acetamidobenzaldehyde and ammonium acetate, N-(4-(6-(4-nitrophenyl)-4-phenyl-1,3-diazabicyclo[3.1.0]hex-3-ene-2-yl)phenyl)acetamide was obtained in good yield. The newly synthesized compound exhibit interesting photochromic behavior in the solid and solution state. The structure of the synthesized compound was confirmed by elemental analysis, 1H-NMR, 13C-NMR and UV-Visible spectral data.
	M792 Mabrouk El Houssine, Elachqar Abdelrhani, El Hallaoui Abdelilah and Alami Anouar Short Note: 2-[(1-Benzamido-2-methoxy-2-oxoethyl)amino]benzoic Acid Molbank 2013, 2013(1), M792; doi:10.3390/M792 Received: 10 October 2012 / Accepted: 6 January 2013 / Published: 11 January 2013 Show/Hide Abstract | Download PDF Full-text (91 KB) |  Abstract: The carboxylic α,α-diaminoester 2-[(1-benzamido-2-methoxy-2-oxoethyl) amino]benzoic acid is obtained by N-alkylation of methyl α-azido glycinate N-benzoylated with 2-aminobenzoic acid.
	M793 Fulgentius Nelson Lugemwa Short Note: Benzyl 3-deoxy-3-(3,4,5-trimethoxybenzylamino)-β-L-xylopyranoside Molbank 2013, 2013(1), M793; doi:10.3390/M793 Received: 23 January 2013 / Accepted: 1 February 2013 / Published: 6 February 2013 Show/Hide Abstract | Download PDF Full-text (71 KB) |  Abstract: Reaction of 3,4,5-trimethoxybenzylamine and benzyl 2,3-anhydro-β-L-ribopyranoside in refluxing ethanol produced benzyl 3-deoxy-3-(3,4,5-trimethoxybenzylamino)-β-L-xylopyranoside in 72.5% yield. An attempt to synthesize the title compound by reacting neat 3,4,5-trimethoxybenzylamine with benzyl 2,3-anhydro-β-L-ribopyranoside without a solvent produced a dark brown mixture with several decomposition products. The structure of benzyl 3-deoxy-3-(3,4,5-trimethoxybenzylamino)-β-L-xylopyranoside was determined using elemental analysis, 1H-NMR and 13C-NMR and its conformation is 1C4.
	M794 Nawal Mishriky and Aisha M. Moustafa Short Note: 2-(4-Methylpiperazin-1-yl)-4-phenyl-6-(thiophen-2-yl)-pyridine-3-carbonitrile Molbank 2013, 2013(1), M794; doi:10.3390/M794 Received: 19 December 2012 / Accepted: 18 February 2013 / Published: 27 February 2013 Show/Hide Abstract | Download PDF Full-text (374 KB) |  Abstract: 2-(4-Methylpiperazin-1-yl)-4-phenyl-6-(thiophen-2-yl)-pyridine-3-carbonitrile (4) was synthesized via nucleophilic substitution reaction of 1-methylpiperazine with 2-bromo analogue 3. The latter was obtained through bromination (Br2/AcOH) of 2-[3-oxo-1-phenyl-3-(thiophen-2-yl)propyl]malononitrile (2).
	M795 Thimo Huber, Lennart Niehues, Carlos Cativiela, M. G. Finn and David Díaz Díaz Short Note: 6,6'-(1E,1'E)-((1R,2R)-1,2-Diphenylethane-1,2-diyl)bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)bis(2-tert-butyl-4-((trimethylsilyl)ethynyl)phenol) Molbank 2013, 2013(1), M795; doi:10.3390/M795 Received: 4 January 2013 / Accepted: 28 February 2013 / Published: 1 March 2013 Show/Hide Abstract | Download PDF Full-text (129 KB) |  Abstract: Functionalizable salen derivative, 6,6'-(1E,1'E)-((1R,2R)-1,2-diphenylethane-1,2-diyl)bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)bis(2-tert-butyl-4-((trimethylsilyl) ethyn-yl)phenol) (3), was synthesized by condensation between (1R,2R)-1,2-diphenylethane-1,2-diamine (2) and 3-tert-butyl-2-hydroxy-5-((trimethylsilyl)ethynyl) benzaldehyde (1) under refluxing conditions. The title compound was characterized by 1H-NMR, 13C-NMR, FT-IR, high-resolution mass spectrometry, optical rotation and melting point determination.
	M796 Shimoga D. Ganesh, Karkala V. Pai and Mahadevappa Y. Karidurganavar Short Note: 4'-Bromophenyl Triptycene-2,5-diol Molbank 2013, 2013(1), M796; doi:10.3390/M796 Received: 8 January 2013 / Accepted: 28 February 2013 / Published: 6 March 2013 Show/Hide Abstract | Download PDF Full-text (122 KB) |  Abstract: Diels Alder reaction of 4-bromophenylquinone (Br-PQ) with anthracene, followed by reduction affords the desired 4'-bromophenyl triptycene-2,5-diol (T-Br-PH). The described synthesis represents a simple and efficient method for the construction of a triptycene ring with a bromophenyl pendant. The intermediate and the final compound (T-Br-PH) have been characterized by elemental analysis, NMR, and LCMS techniques.
