Abstract. Enterovesical fistula (EVF) is a rare complication of diverticulitis, as well as Crohn's disease, intestinal malignancy, radiotherapy and trauma. EVF formation is associated with inflammation of the involved bowel segments. The current study presents the case of a 35-year-old man with non-Hodgkin's lymphoma who developed pneumaturia, fecaluria and recurrent urinary tract infections following chemotherapy, accompanied by regressive change of the lymphoma. Abdominal computed tomography scans revealed that the terminal ileum had adhered to the bladder wall. The patient underwent exploratory laparotomy and partial resection of the terminal ileum, and EVF was confirmed. Histological examination revealed an inflammatory response but no evidence of residual lymphoma. The diagnosis of EVF is occasionally difficult and requires appropriate radiographic examination. Surgical treatment is recommended.

The synthesis starts directly from salicylic aldehyde derivatives and succeeds in a one-pot procedure with comparable yields. During the reaction of amides, the N-acyl group is not transferred and, thus, substitution patterns with three different substituents are possible. -(SYU, S.-E.; LEE, Y.-T.; JANG, Y.-J.; LIN*, W.; Org.

Chemoselective Synthesis of Tetrasubstituted Furans via Intramolecular Wittig Reactions: Mechanism and Theoretical Analysis. -Tetrasubstituted furans (III) and (VII) are synthesized from the corresponding α,β-unsaturated ketones (I) and (V), acid chlorides (II) and (VI), and Bu3P via chemoselective intramolecular Wittig reaction as the key step. The presence of an additional electron-withdrawing group in the α-position of Michael acceptors (I) and (V) determines the chemoselectivities of presumable phosphorous ylides in the Wittig reaction. -(LEE, Y.-T.; LEE, Y.-T.; LEE, C.-J.; SHEU, C.-N.; LIN, B.-Y.; WANG*, J.-H.; LIN, W.; Org.

The process is chemoselective and affords highly functionalized products in moderate to good yields, however, with only low diastereoselectivity.

The title reaction provides mild and diastereoselective approach to β‐amino ketones.
