Introduction. While the incidence of pancreatic cystic lesions has steadily increased, we sought to evaluate the changes in their surgical management. Methods. Patients with pancreatic cystic lesions who underwent surgical resection from 2003 to 2013 were identified. Clinicopathologic factors...

Facile 1,3-diaza-Claisen rearrangements of tertiary allylic amines bearing an electron-deficient alkene.

Organic letters

Aranha RM, Bowser AM, Madalengoitia JS.
PMID: 19125576
Org Lett. 2009 Feb 05;11(3):575-8. doi: 10.1021/ol802577z.

Tertiary allylic amines with an electron-deficient alkene react with isocyanates and isothiocyanates to give highly substituted ureas and thioureas arising from formal 1,3-diaza-Claisen rearrangements. Isocyanates and isothiocyanates with strong electron-withdrawing groups are more reactive. Similarly, the data suggest that...
