[Blood purification therapy of gestational hyperlipidemic pancreatitis: a case report].

Gestational hyperlipidemic pancreatitis is an uncommon complication of pregnancy that incurs a high risk of morbidity and mortality of both maternal and fetal patients. We described the response of continous renal replacement therapy in a woman with extreme gestational hyperlipidemia and severe pancreatitis. Five consecutive plasma exchanges didn't lead to a remarkable reduction (10.

An expedient route to Montanine-type Amaryllidaceae alkaloids: total syntheses of (-)-brunsvigine and (-)-manthine.

The first total syntheses of (-)-brunsvigine (1) and (-)-manthine (2) were accomplished in 10 and 18 steps, respectively. (-)-Quinic acid was converted to enone 12 in five steps. Iodination of enone 12 followed by stereoselective reduction yielded alpha-iodo allylic alcohol 16.
