A Specific Nucleophilic Ring-Opening Reaction of Aziridines as a Unique Platform for the Construction of Hydrogen Polysulfides Sensors
نویسندگان
چکیده
A hydrogen polysulfide mediated aziridine ring-opening reaction was discovered. Based on this reaction, a novel H2S(n)-specific chemosensor (AP) was developed. AP showed high sensitivity and selectivity for H2S(n). Notably, the fluorescent turn-on product (1) exhibited excellent two-photon photophysical properties, a large Stokes shift, and high solid state luminescent efficiency.

Lewis acid mediated nucleophilic ring opening followed by cycloaddition of 2-aryl-N-tosylaziridines with carbonyl compounds: further support towards an SN2-type mechanism
A highly regioselective SN2-type ring opening of 2-aryl-N-tosylaziridines with carbonyl compounds in the presence of a Lewis acid to afford various 1,3-oxazolidines and 1,2-amino alcohols in excellent yields and moderate to high enantioselectivity is described. The formation of non-racemic products provides convincing evidence for the SN2-type ring opening mechanism. 2007 Elsevier Ltd. All righ...
متن کاملRing-opening reaction of Bus- and SES-protected aziridines using lithiated dithianes.
The scope and limitation of the ring-opening reaction of sulfonyl-activated aziridines using lithiated dithianes was investigated. Nucleophilic attack of lithiated dithianes on aziridines containing tert-butylsulfonyl (Bus) and 2-(trimethylsilyl)ethylsulfonyl (SES) demonstrated efficient ring cleavage to yield beta-amino carbonyl equivalents, gamma-lactam and syn- and anti-1,5-aminoalcohols. Th...
متن کاملOpposite regiospecific ring opening of 2-(cyanomethyl)aziridines by hydrogen bromide and benzyl bromide: experimental study and theoretical rationalization.
Ring opening of 1-arylmethyl-2-(cyanomethyl)aziridines with HBr afforded 3-(arylmethyl)amino-4-bromobutyronitriles via regiospecific ring opening at the unsubstituted aziridine carbon. Previous experimental and theoretical reports show treatment of the same compounds with benzyl bromide to furnish 4-amino-3-bromobutanenitriles through ring opening at the substituted aziridine carbon. To gain in...
متن کاملEfficient Regioselective Ring Opening of Activated Aziridine-2-Carboxylates with [18F]Fluoride
Aziridines can undergo a range of ring-opening reactions with nucleophiles. The regio- and stereochemistry of the products depend on the substituents on the aziridine. Aziridine ring-opening reactions have rarely been used in radiosynthesis. Herein we report the ring opening of activated aziridine-2-carboxylates with [(18)F]fluoride. The aziridine was activated for nucleophilic attack by substi...

A conceptually new, simple and practical method for the syn-nucleophilic displacement of aryl and vinyl epoxides and aryl aziridines with (substituted) phenols, using aryl borates as activating nucleophiles under neutral conditions, is reported.
