TIME TO LIFT LEG DEPENDS ON INITIAL WEIGHT DISTRIBUTION

INTRODUCTION: If you are a defensive player of football or basketball, you must have an experience that you were impotently left behind the offensive player while you certainly knew he/she cut back to left and you should have stepped to left. Why this happen? As a basic research to answer this question, we conducted the lift-one-leg task from quiet standing with and without visual feedback of weight distribution. We hypothesized that the time to lift leg depends on the initial weight distribution. The aim of the present study is to investigate if and how much the initial weight distribution during quiet standing influences the time to lift leg

Helical Nanographenes Embedded with Contiguous Azulene Units

うねり構造をもつグラフェンナノリボンの精密合成に成功 --非ベンゼノイド構造の新規構築反応を開発--. 京都大学プレスリリース. 2020-07-20.The azulene moiety, composed of contiguous pentagonal and heptagonal rings, is a structural defect that alters the electronic, magnetic, and structural properties of graphenes and graphene nanoribbons. However, nanographenes embedded with an azulene cluster have not been widely investigated because these compounds are difficult to synthesize in their pure form. Herein, azulene-embedded nanographenes bearing a unique cove-type edge were synthesized by a novel synthetic protocol. Experimental and theoretical investigations revealed that this cove edge imparts stable helical chirality, unlike normal cove edges. The in-solution self-association behavior and the structural, electronic, and electrochemical properties were also described in detail

Optical resolution via catalytic generation of chiral auxiliary

A new catalytic method for separating enantiomers of racemic compounds is proposed. Catalytic asymmetric addition of chiral trans-2-substituted cyclohexanols to imines provided diastereomeric mixtures of aminals, and the subsequent separation of the enantiomers by silicagel column chromatography and the hydrolysis of the aminals produced the alcohols in an optically active form

Oxa- and Azacycle-formation via Migrative Cyclization of Sulfonylalkynol and Sulfonylalkynamide with NHeterocyclic Carbene

An N-heterocyclic carbene promotes cyclization of sulfonylalkynols and sulfonylalkynamides that accompanies 1,2-migration of the sulfonyl groups. This reaction provides a novel access to oxa- and azacycles possessing a pendent vinyl sulfone functionality, which in turn is amenable for further transformations

Striking Difference between Succinimidomethyl and Phthalimidomethyl Radicals in Conjugate Addition to Alkylidenemalonate Initiated by Dimethylzinc

We used dimethylzinc to develop a conjugate addition reaction of imidomethyl radicals to alkylidenemalonates using dimethylzinc, in which we observed a significant difference between succinimidomethyl and phthalimidomethyl radicals. This reaction provides new access to γ- aminobutyric acid derivatives, which often function as neurotransmitters

Site-selective benzoin-type cyclization of unsymmetrical dialdoses catalyzed by N-heterocyclic carbenes for divergent cyclitol synthesis

A highly site-selective N-heterocyclic carbene (NHC)-catalyzed benzoin-type cyclization of unsymmetrical dialdoses is developed to enable a divergent cyclitol synthesis. The choice of chiral NHCs and protecting groups affects the site-selectivity. The resulting inososes are converted into epi-, muco- and myo-inositol, and their chiral protected derivatives are formed in good yields
