directing group screening to enable olefin difunctionalization with high levels of regio-, chemo-, and diastereocontrol. This general and practical protocol is compatible with α- or β-substituted terminal alkenes and internalalkenes, providing rapid access to branched aliphatic amines bearing two skipped and vicinal stereocenters with high diastereoselectivities that would otherwise be difficult to synthesize

compositions of the alcohol mixtures formed in nitrousaciddeaminations of cyclopropylmethylcarbinylamine, (2-methylcyclopropyl)-carbinylamine, 2-methylcyclobutylamine, 3-methylcyclobutylamine, crotylcarbinylamine and allylmethylcarbinylamine have been determined. These results and the behavior of the corresponding alcohols under isomerization conditions in strongly acidic media may be explained by assuming formation

The present invention relates to macrocyclic pyridotriazine derivatives of formula (I) and the pharmaceutically acceptable salts, solvates or or polymorph thereof, and the use of such compounds as a medicament, in particular in the prevention and/or treatment of viral infections caused by viruses belonging to the Orthomyxoviridae famiIy. The present invention furthermore relates to pharmaceutical compositions or combination preparations of the compounds, and to the compositions or preparations for use as a medicament, more preferably for the prevention or treatment of viral infections caused by viruses belonging to the Orthomyxoviridae family.
Rhodium-catalysed reactions of 5-aminopent-1-enes with carbon monoxide and hydrogen give 2-piperidinone derivatives in high yields under mild conditions. Reaction of allylamine under similar conditions gave exclusively 2-pyrrolidone in high yield and reactions of 4-aminobut-1-enes gave mixtures of 2-piperidinones and 2-pyrrolidinones. The role of the hydrogen in these reactions is discussed.

We have observed a remarkable rearrangement while attempting to prepare 4-penten-2-ylarnine (I) through the reaction of the Grignard reagent derived from 4-penten-2-yl chloride (II) with methoxylamine, in that part of the amine formed appeared to be 2-methyl-3-butenylamine (III).
我们在尝试通过衍生自 4-戊烯-2-基氯 (II) 的格氏试剂与甲氧基胺反应制备 4-戊烯-2-基拉宁 (I) 时观察到了显着的重排,在形成的那部分胺中似乎是 2-甲基-3-丁烯胺 (III)。
