bioactive and medicinally relevant molecules. Historically, the formal hydroazidation of simple activatedolefins and styrenes has proven difficult due to the inherent propensity of these compounds to oligomerize. Herein is disclosed a method for the anti-Markovnikov hydroazidation of activatedolefins, catalyzed by an organic acridinium salt under irradiation from blue LEDs. This method is applicable
Embodiments of the present disclosure describe substituted phenethylamine derivatives, compositions comprising the substituted phenethylamine derivatives, methods of making the substituted phenethylamine derivatives, and methods of using the phenethylamine derivatives, and the like. Exemplary compounds of the present disclosure include compounds of the formula (I) and (II):

In a continuation of our studies into 4-Amino-3,4-dihydro-2H-naphthalen-1-ones as novel modulators of allergic and inflammatory phenomena, we have extended our work to include dimeric analogues. Of these derivatives, the most promising activity was seen with tertiary amine 58a, which exhibited potent mast cell-stabilising activity in vitro against a variety of stimuli and also in vivo against passive cutaneous anaphylaxis.

Late‐Stage Dehydroxyazidation of Alcohols Promoted by Trifunctional Hypervalent Azido‐Iodine(III) Reagents
We developed a mild, metal-free practical method for late-stage dehydroxyazidation of structurally complex alcohols promoted by trifunctional hypervalent azido-iodine(III) reagents ABZ. The reactions proceeded via an SN2 pathway and showed excellent chemoselectivity and stereospecificity and gave the corresponding azides in high yields. The reaction mechanism was investigated by means of experiments

in rat and guinea pig brain. Here, we report the synthesis and biological evaluation of additional PAT analogues in order to identify differences in binding at these twosites. Further molecular modifications involve the pendant phenyl ring as well as quaternary amine compounds. Comparison of about 38 PAT analogues, 10 structurally diverse H(1) ligands, and several other CNS-active compounds revealed
