Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C-H and C-C bonds was accessible to the one-pot substitution reaction.
Use of fenoterol and fenoterol analogues in the treatment of glioblastomas and astrocytomas

Page/Page column 36; 55, (2016/12/07)
This disclosure concerns the discovery of the use of fenoterol and (R,R)- and (R,S)-fenoterol analogs for the treatment of a tumor expressing a β2-adrenergic receptor, such as a primary brain tumor, including a glioblastoma or astrocytoma expressing a β2-adrenergic receptor. In one example, the method includes administering to a subject a therapeutically effective amount of fenoterol, a specific fenoterol analog or a combination thereof to reduce one or more symptoms associated with the tumor, thereby treating the tumor in the subject.

An efficient and selective bis(amidate)bis(amido) titanium precatalyst for the anti-Markovnikov hydroamination of alkynes is reported. Hydroamination of terminal and internal alkynes with primary alkylamines, arylamines, and hydrazines is promoted by 5-10 mol % of Ti catalyst. Various functional groups are tolerated including esters, protected alcohols, and imines. The in situ generated complex shows comparable catalytic activity, demonstrating its synthetic versatility for benchtop application. Applications of this catalyst for the synthesis of amino alcohols and a one-pot procedure for indole synthesis are described. A mechanistic proposal that invokes turnover-limiting protonolysis is presented to rationalize the observed regioselectivities.
