Series of thirteen 1-[(2-chlorophenyl)carbamoyl]naphthalen-2-yl carbamates and thirteen 1-[(2-nitrophenyl)carbamoyl]naphthalen-2-yl carbamates with alkyl/cycloalkyl/arylalkyl chains were prepared and characterized. Primary in vitro screening of the synthesized compounds was performed against Staphylococcus aureus, two methicillin-resistant S. aureus strains, Mycobacterium marinum, and M. kansas...
A series of naphthalenyl-substituted arenediynes were prepared to examine photochemical reactivity. For naphthalen-1-ylethynyl arenediyne, 350 nm photolysis resulted in a tandem [2 + 2] photocycloaddition to afford cyclobutene adducts. For naphthalen-2-ylethynyl derivatives, electron-donating methoxy substituents were found to facilitate C(1)-C(6) Bergman cyclization at 300 nm. Theoretical calc...
Eight 1-[(2-chlorophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates and eight 1-[(2-nitrophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates were tested for their activity related to the inhibition of photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. The PET-inhibiting activity of the compounds was relatively low; the corresponding IC50 values ranged from 0.05 ...
A gold(I)-catalyzed 6-endo-dig cyclization of aromatic 1,5-enyne was developed to synthesize 2-(naphthalen-2-yl)aniline. The functional group tolerance this examined systematically and a possible mechanism proposed. derivatization 2-(naphthalen-2-yl)aniline carried out facile access benzo[α]carbazole, benzo[c,h]cinnoline dibenzo[i]phenanthridine derivatives in divergent way.
The complex structure of aminobenzylnaphthols can be easily obtained with the useful Betti reaction. These valuable compounds give rise to chiral intermediates, that found wide application in asymmetric synthesis. 1-[(1S)-(4-Fluorophenyl)-((1′S)-1′-naphthalen-1-yl-ethylamino)-methyl]-naphthalen-2-ol 1 was treated triflic anhydride yield corresponding (S,S)-triflate 2, which is a intermediate fu...
The title compound, C(32)H(36)Br(2)O(2), was prepared by the reaction of 6-bromo-1-(2-bromo-6-hydroxy-naphthalen-5-yl)-naphthalen-2-ol and 1-iodo-hexane. The dihedral angle between the naphthalene ring planes is 63.8 (9)° The crystal structure may be stabilized by two very weak π-π inter-actions involving the six-membered rings, with centroid-centroid distances of 4.012 (4) and 4.010 (4) Å. The...
به منظور مطالعه تاثیر سایکوسل و نفتالن استیک اسید بر عملکرد اسانس و پیکره رویشی گیاه شمعدانی عطری تحقیقی به صورت فاکتوریل، در قالب طرح بلوک‌های کامل تصادفی در سه تکرار در سال 1388 در گلخانه تحقیقاتی و آزمایشگاه گروه علوم باغبانی دانشگاه زنجان اجرا شد. تیمارها شامل دو نوبت اسپری برگی ماهانه محلول نفتالن استیک اسید در چهار سطح (0، 40، 80، 120 میلی‌گرم در لیتر) و محلول سایکوسل با غلظتهای (0، 500،...
