Hyperlipidemia, fatty liver, hypertension, endoscopic retrograde cholangiopancreatography treatment, acute hyperglycemia, elevated lactate dehydrogenase and creatine kinase, decreased calcium, and AB blood type were risk factors for hyperglycemia development after AP.

Diastereo- and enantioselective oxa-Nazarov cyclization-Michael addition of conjugated 1,2-diketones was achieved by using an asymmetric binary-acid catalysis with chiral phosphoric acid and FeBr3. The reaction affords the corresponding chiral 3(2H)-furanones...

Herein we report Lewis acid HfCl4-catalyzed [4 + 2] cycloaddition between β,γ-unsaturated α-keto esters and various symmetric or unsymmetric alkynes, giving the desired polysubstituted 4H-pyrans in up to 98% yield and with excellent regioselectivity (>99:1) via a vinyl carbocation under mild conditions.
