[A Case of Spinal Epidural Hematoma Presenting with Transient Hemiplegia].

We report a rare case of a patient with spinal epidural hematoma who presented with transient hemiplegia. A 90-year-old man awakened from sleep due to sudden neck pain. Fifteen minutes later, the man experienced progressively worsening weakness in his left hand, and was transported in an ambulance to our hospital.

[Surgical treatment for gall bladder cancer with a confluence stone-a case report].

The patient was a 71-year-old man. In September 2011, he experienced abdominal pain with high fever. Abdominal computed tomography (CT) diagnosed acute cholecystitis with a confluence stone (corlette classification type II).

Synthesis of (±)-8-deisopropyladunctin B.

(±)-8-Deisopropyladunctin B, the deisopropyl form of adunctin B, which was isolated from the leaves of Piper aduncum (Piperaceae) collected in Papua New Guinea, was synthesized in 0.77% overall yield in 17 steps from 5,7-dimethoxycoumarin-3-carboxylate. The key step was our original stereoconvergent skeleton transformation from 1,2,2a,8b-tetrahydro-3H-benzo[b]cyclobuta[d]pyran-3-one to 1,2,4a,9b-tetrahydrodibenzofuran-4-ol with dimethylsulfoxonium methylide.
