Ring-Chain Isomerism of N-(3-Hydroxyalkyl)nitrones, I. - C-Aryl-N-(3-hydroxypropyl)nitronesN-(3-Hydroxypropyl) nitrones 5 are prepared from 3-(hydroxyamino) propanol 3 and aromatic aldehydes. The isomerism between the open-chain nitrone form 5 and the cyclic perhydro-1,3-oxazine form 6 is proved by formation of diphenylboron chelates 4 and N-acyloxy-perhydro-1,3-oxazines 10, respectively.
Notes:
Aus 3-(Hydroxyamino)propanol 3 und aromatischen Aldehyden werden N-(3-Hydroxypropyl)-nitrone 5 dargestellt. Die Isomerie zwischen offenkettiger Nitron-Form 5 und cyclischer Perhydro-1,3-oxazin-Form 6 wird durch Bildung von Diphenylborchelaten 4 bzw. N-Acyloxy-perhydro-1,3-oxazinen 10 nachgewiesen.
