A BEt3-Base catalyst for amide reduction with silane

Reported herein is the development of a simple but practical catalytic system for the selective reduction of amides with hydrosilane or hydrosiloxane. Low-cost and readily available triethylborane (1.0 M in THF), in combination with a catalytic amount of an alkali metal base, was found to catalyze the reduction of all three amide classes (tertiary, secondary, and primary amides) to form amines under mild conditions. In addition, the selective transformation of secondary amides to aldimines and primary amides to nitriles can also be achieved by using a proper combination of BEt3 and base. The scope of these BEt3-base-catalyzed amide hydrosilylation reactions has been explored in depth. Preliminary results of mechanistic studies suggest a modified Piers’ silane Si-H¡¤¡¤¡¤B activation mode wherein the hydride abstraction by BEt3 is promoted by the coordination of an alkoxide or hydroxide anion to the Si center.

Synthesis and in vitro evaluation of imidazo[1,2- b ]pyridazines as ligands for beta-amyloid plaques

A series of imidazo[1,2-b]pyridazine derivatives were synthesized and evaluated for binding to amyloid plaques in vitro using synthetic aggregates of Abeta1?40. Binding affinities of these compounds were found to range from 11.0 to >1000 nM, depending on the various substitution patterns in the 6-position and 2-position. 2-(4?-Dimethylaminophenyl)-6- (methylthio)imidazo[1,2-b]pyridazine (4) showed high binding affinity (K i = 11.0 nM) and might be useful for the development of novel positron emission tomography radiotracers for imaging Abeta plaques.

Silyl Radical Activation of Alkyl Halides in Metallaphotoredox Catalysis: A Unique Pathway for Cross-Electrophile Coupling

A strategy for cross-electrophile coupling has been developed via the merger of photoredox and transition metal catalysis. In this report, we demonstrate the use of commercially available tris(trimethylsilyl)silane with metallaphotoredox catalysis to efficiently couple alkyl bromides with aryl or heteroaryl bromides in excellent yields. We hypothesize that a photocatalytically generated silyl radical species can perform halogen-atom abstraction to activate alkyl halides as nucleophilic cross-coupling partners. This protocol allows the use of mild yet robust conditions to construct Csp3-Csp2 bonds generically via a unique cross-coupling pathway.

LIGANDS FOR CARDIAC BETA1 ADRENORECEPTOR FOR IMAGING CONGESTIVE HEART FAILURE

Novel beta1 adrenoreceptor ligands that find use as imaging agents within nuclear medicine applications (e.g., PET imaging and SPECT imaging) are provided. Methods of imaging, including methods of imaging congestive heart failure, are also provided. The novel compounds may exhibit high affinity and selectivity, minimal metabolism, minimalnon-specific binding and have a favorable log P value (< 0). In some instances, beta 1-AR selective ligands are conjugated to an imaging moiety in such a way that it does not impact the antagonist affinity and their use. In other instances, the conjugation may be directly to the antagonist at several sites that will not impact affinity. In further instances, the conjugation may be by means of a linking group, which can be used to alter the pharmacokinetics and clearance of the complex The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
