Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

European Journal of Organic Chemistry, EarlyView.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Genetic landscape of patients with atypical absence status epilepticus: A systematic review

Epilepsia Open, EarlyView.
Abstract Atypical absence status epilepticus (AASE) is a rare subtype of nonconvulsive status epilepticus (NCSE), characterized by clouding of consciousness and continuous or fluctuating epileptiform activity, generally at a frequency below 3 Hz. Only sparse literature exists on the genetic conditions associated with it.

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

Energy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents
