Approach to Fully Substituted Cyclic Nitrones from N‐Hydroxylactam Derivatives: Development and Application to the Total Synthesis of Cylindricine C

Angewandte Chemie - International Edition, 2019
An approach to cyclic nitrones from N-hydroxylactam derivatives is documented. The nucleophilic addition of an organolithium reagent to an N-OSEM [SEM=2-(trimethylsilyl)ethoxymethyl] lactam forms a five-membered chelated intermediate, which undergoes ...

Nitrones and oxaziridines. VIII. Cycloaddition reactions of nitrones with isothiocyanates

Australian Journal of Chemistry, 1973
Whereas nitrones undergo cycloaddition to the C=N double bond of phenyl isothiocyanate, predominant addition to the C=S double bond of substituted phenyl isothiocyanates, methyl isothiocyanate and benzoyl isothiocyanate occurs. However, these cycloadducts are not stable but undergo fragmentation usually with the formation of thioamides and isocyanates.
