Sub-Acute Effects of Psilocybin on Empathy, Creative Thinking, and Subjective Well-Being.

Creative thinking and empathy are crucial for everyday interactions and subjective well-being. This is emphasized by studies showing a reduction in these skills in populations where social interaction and subjective well-being are significantly compromised (e.g.

Analysis of six 'neuro-enhancing' phenidate analogs.

Six collected phenidates, i.e., 4-methylmethylphenidate, 3,4-dichloromethylphenidate, ethylphenidate, 3,4-dichloroethylphenidate, ethylnaphthidate, and N-benzyl-ethylphenidate were fully characterized by means of X-ray, nuclear magnetic resonance (NMR), gas chromatography-mass spectrometry (GC-MS), electrospray ionization-tandem mass spectrometry (ESI-MS/MS), attenuated total reflectance Fourier transform infrared (ATR-FTIR) and GC solid-state IR analysis.

Catalytic asymmetric Claisen rearrangement of Gosteli-type allyl vinyl ethers: total synthesis of (-)-9,10-dihydroecklonialactone B.

The enantioselective synthesis of (-)-9,10-dihydroecklonialactone B is described. The catalytic asymmetric Claisen rearrangement of a Gosteli-type allyl vinyl ether was utilized to afford an acyclic α-keto ester building block endowed with functionality amenable to the preparation of the carbocyclic target molecule by suitable postrearrangement transformations: A highly diastereoselective Corey-Bakshi-Shibata reduction of a β-chiral α-keto ester and a reductive homologation of an α-hydroxy ester. A transprotection tactic by a chemoselective intramolecular 6-exo-trig iodoetherification enabled regioselective ring-closing alkene metatheses to afford the 5- as well as the 14-membered ring, however, with mixed success in terms of E/Z selectivity.

Total synthesis of (-)-ecklonialactone B.

The total synthesis of (-)-ecklonialactone B as well as the 9,10-dihydro derivative by two different strategies is reported. The catalytic asymmetric Claisen rearrangement of Gosteli-type allyl vinyl ethers delivered elaborated α-keto ester building blocks. Ring-closing metatheses, including a notable diastereotopos-differentiating variant, a B-alkyl Suzuki-Miyaura cross-coupling reaction and a regio- and diastereoselective last-step epoxidation are key contributors.

The awesome Asthma School Days Program: educating children, inspiring a community.

Program planners developed an educational program to improve the health of children with asthma in grades three to five in Milwaukee (Wis.) Public Schools. During 1997-1998, 1,400 students from 74 elementary schools participated in the Awesome Asthma School Days education program.
