The asymmetric ring-opening of meso-aziridines with primary alcohols is realized using an N,N'-dioxide-Mg(OTf)2 complex as the catalyst. The desired vicinal trans-β-amino ethers are afforded in good yields and enantioselectivities. Aniline and water could also be used as the nucleophiles for the ring-opening in an identical catalyst system.
This article describes the implementation and initial assessment of a training blog created within a family medicine department and used as a feedback mechanism for residents. First-year residents (n = 7) at a large private East Coast university hospital had an interaction with a patient recorded and posted to a training blog. The residents then watched(More)

A highly efficient aza-Friedel-Crafts reaction of sesamol with aldimines has been realized by using a chiral N,N'-dioxide-scandium(III) complex as the catalyst. A series of corresponding bioactive chiral α-amino-sesamols were obtained in moderate to good yields (up to 97%) with excellent enantioselectivities (up to 97% ee). Furthermore, the control(More)
A highly efficient asymmetric ring-opening/cyclization/retro-Mannich reaction of cyclopropyl ketones with aryl 1,2-diamines has been realized using a chiral N,N'-dioxide/Sc(III) catalyst. Benzimidazoles containing chiral side chains were generated under mild reaction conditions in excellent outcomes (up to 99 % yield and 97 % ee). This method also provides(More)
An N,N'-dioxide/scandium(III) complex catalyzed, highly efficient conjugate addition of malonic esters to enynes is described. A range of trisubstituted 1,2-allenyl ketones were obtained in high yields (up to 99 %) with good d.r. (up to 95/5) and excellent ee values (97 %-99 %). Moreover, the products could be easily transformed into chiral furan and(More)
It is suggested and demonstrated that two specific 2-dimensional correlation patterns, fixed-to-arbitrary bin and neighboring bin correlation patterns, are efficient for identifying various random multiplicative cascade processes. A possible application of these two correlation patterns to single event analysis in Relativistic Heavy Ion Collider experiments(More)
A highly enantioselective tandem Michael/ring-closure reaction of α,β-unsaturated pyrazoleamides and amidomalonates has been accomplished in the presence of a chiral N,N'-dioxide-Yb(OTf)3 complex (Tf: trifluoromethanesulfonyl) to give various substituted chiral glutarimides with high yields and diastereo- and enantioselectivities. Moreover, this methodology(More)
A simple and efficient acylative kinetic resolution of racemic mandelic acid esters was accomplished with a chiral N,N'-dioxide-scandium(III) complex under mild and base-free reaction conditions. A variety of mandelic acid esters performed well in the reaction, obtaining both acylated products (up to 49% yield, 97% ee) and recovered substrates (up to 49%(More)
