Analysis of mental health status and related factors in patients with acute cerebral infarction.

Background: Acute cerebral infarction (ACI) is characterized by a high incidence of morbidity, disability, recurrence, death and heavy economic burden, and has become a disease of concern in global researchers. As ACI has serious effects on patients' physical status, life and economy, often causing anxiety, depression and other psychological problems, these problems can lead to the aggravation of physical symptoms; thus, it is very important to understand the factors affecting the mental health of these patients.

Aim: To understand the elements that affect the mental health of patients who have suffered an ACI.

Construction of sulfur-containing -vinylimides: -addition of imides to propargyl sulfonium salts.

An -addition reaction between imides and propargyl sulfonium salts was developed to afford sulfur-containing -vinylimides with moderate to excellent yields. Under the activation of NaOAc·3HO, imides could undergo deprotonation and propargyl sulfonium salts could isomerize to allenic sulfonium salts. The -nucleophilic attack initiates the reaction and gives the desired products.
