Prognostic factors influencing the survival of patients with carcinoma of the gastric cardia receiving preoperative interventional embolization chemotherapy.

The purpose of this study was to analyze the characteristics of patients with gastric cardia cancer (GCC) to identify the main factors the influence the survival rate after interventional embolization chemotherapy (IEC). One hundred and fifty-six patients with advanced GCC were treated with IEC via the left gastric artery. Survival time was defined as from the date of diagnosis until death or the end of this study in June 2015.

Synthesis of 3-pyrrolin-2-ones by rhodium-catalyzed transannulation of 1-sulfonyl-1,2,3-triazole with ketene silyl acetal.

α-Imino rhodium carbenoids generated from 1-sulfonyl 1,2,3-triazole were applied to the 3 + 2 cycloaddition with ketene silyl acetal, offering a novel and straightforward synthesis of biologically interesting compound 3-pyrrolin-2-one with broad substrate scope.

Synthesis of 3-aza-bicyclo[3.1.0]hexan-2-one derivatives via gold-catalyzed oxidative cyclopropanation of N-allylynamides.

N-allylynamides with various functional groups and different substitution patterns can be converted into 3-aza-bicyclo[3.1.0]hexan-2-one derivatives in moderate to high yield using IMesAuCl/AgBF4 as the catalyst and pyridine N-oxide as the oxidant.
