Conversions by Dimethyldioxirane of 1-Alkylbenzotriazoles into Their N-Oxides and of 2-Alkylbenzotriazoles into 2-Alkyl-trans-4,5,6,7-diepoxy-4,5,6,7-tetrahydrobenzotriazoles

open access: yes, 2016
Dimethyldioxirane converted 1-alkylbenzotriazoles 4 to the corresponding 3-alkylbenzotriazole 1-oxides 5 in good yields, but transformed 2-alkylbenzotriazoles 12 into 2-alkyl-trans-4,5,6,7-diepoxy-4,5,6,7-tetrahydrobenzotriazoles ...

Esterase-Sensitive Nitric Oxide Donors of the Diazeniumdiolate Family:  In Vitro Antileukemic Activity

open access: yes, 2016
We have designed a novel prodrug class that is stable in neutral aqueous media but releases bioactive nitric oxide (NO) on metabolism by esterase. Diazeniumdiolates of structure R2N−N(O)N−OR‘, in which R‘ = Na, were reacted with BrCH2OAc to convert the ...

Syntheses of 1-Alkyl-1,2,4-triazoles and the Formation of Quaternary 1-Alkyl-4-polyfluoroalkyl-1,2,4-triazolium Salts Leading to Ionic Liquids

open access: yes, 2016
1,2,4-Triazole was alkylated (alkyl = methyl, butyl, heptyl, decyl) at N-1 in >90% isolated yields. The resulting 1-alkyl triazoles were quaternized at N-4 in >98% isolated yields using fluorinated alkyl halides with >98% isolated yields, under neat ...

Herbicidal action of 2-hydroxy-3-alkyl-1,4-naphthoquinones

open access: yes, 2002
The main mode of herbicidal activity of 2-hydroxy-3-alkyl-1,4-naphthoquinones is shown to be inhibition of photosystem II (PSII). The herbicidal and in vitro activities have been measured and correlated with their (Log)octanol/water partition ...

Synthesis and Anti-HIV-1 Activity of a Series of 1-Alkoxy-5-alkyl-6-(arylthio)uracils

open access: yes, 2016
A series of 1-alkoxy-5-alkyl-6-(arylthio)uracils was synthesized and tested for their ability to inhibit HIV-1 replication. Treatment of 2-alkyl-3,3-bis(methylthio)acryloyl chlorides (5a−e) with AgOCN in benzene followed by reaction of the resulting ...
