tin–lithium exchange from stannylated allylamines and are suitable nucleophiles for a wide range of conversions. With aldehydes and ketones, aminomethylated allyl alcohols are formed, whereas the reaction with α-brominated ketones gives rise to vinyl epoxides or aldehydes, depending on the reaction and workup conditions used.
The trading of space for time under weakly activated catalysis: expeditious synthesis of β-NH<sub>2</sub> alcohols <i>via</i> a direct ammonolysis of epoxides with ammonia
The direct synthesis of β-NH2 alcoholsvia flexible ammonolysis of epoxides is still a challenging and unresolved problem. Herein, we present a strategy of “trading space for time under weakly activated catalysis” and “shielding the reactivity of the product”, and thereby developed a novel single-step ammonolysis reaction of epoxides with ammonia. A stoichiometric amount of HCO2NH4 as an additive plays

The mechanism of rearrangement of beta-hydroxyethyl-(1,2,4-triazoles) has been shown using crossover experiments to be intermolecular and free energy profiles show that reactions are thermodynamically-controlled.

A series of p-hydroxybenzenesulphonamides ER beta receptor agonists were discovered and several compounds identified had excellent selectivity over the related ER alpha receptor. One of these, compound 11, had an interesting binding conformation determined by X-ray and represents an excellent starting point in the quest for further selective ER beta agonists.
