Preparation of sterically congested 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane, aromatic acids, cyclopentanone and primary amines
Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig cyclization in CH2Cl2 in excellent yields. The structures of the products were deduced from...

متن کاملTransformation of cultured mouse mammary glands by aromatic amines and amides and their derivatives.
Mouse mammary glands in whole organ culture, previously demonstrated by others to undergo lobuloalveolar develop ment, functional differentiation, and glandular involution, are transformable by carcinogenic aryl amines and amides and their derivatives. The transformation, which involves an escape from the hormonal controls of these processes, results in the formation of nodule-like alveolar les...
متن کاملCondensation of Diacetyl with Alkyl Amines: Synthesis and Reactivity of p-Iminobenzoquinones and p-Diiminobenzoquinones.
Condensation reactions between diacetyl and α-branched primary alkylamines under mild and neutral conditions provided a mixture of 2,5-dimethylbenzoquinone(alkylimines), 2,5-dimethylbenzoquinone(bis-alkyldiimines), and N,N'-dialkyl-2,5-dimethylbenzene-1,4-diamines, which were efficiently separated as pure products by column chromatography. Both 2,5-dimethylbenzoquinone(alkylimines) and 2,5-dime...
متن کاملContinuous-flow synthesis of primary amines: Metal-free reduction of aliphatic and aromatic nitro derivatives with trichlorosilane
The metal-free reduction of nitro compounds to amines mediated by trichlorosilane was successfully performed for the first time under continuous-flow conditions. Aromatic as well as aliphatic nitro derivatives were converted to the corresponding primary amines in high yields and very short reaction times with no need for purification. The methodology was also extended to the synthesis of two sy...
