Since the norepinephrine transporter (NET) is involved in a variety of diseases, the investigation of underlying dysregulation-mechanisms of the norepinephrine (NE) system is of major interest. Based on the previously described highly potent and selective NET ligand 1-(3-(methylamino)-1-phenylpropyl)-3-phenyl-1,3-dihydro-2H-benzimidaz- ol-2-one (Me@APPI), this paper aims at the development of several fluorinated methylaminebased analogs of this compound. The newly synthesized compounds were computationally evaluated for their interactions with the monoamine transporters and represent reference compounds for PET-based investigation of the NET.

Abstract A ruthenium complex modified with (1S,2S)-1,2-diphenyl-1,2-ethanediamine efficiently catalyzes asymmetric hydrogenation of 3-chloro-1-phenylpropan-1-one in the presence of potassium hydroxide solution in isopropyl alcohol, specific optical rotation of the synthesized products reaching -24.6°. Effects of the reaction time, hydrogen pressure, and the alkali concentration on the reaction course have been elucidated.

Boron-homologation reactions represent an efficient and programmable approach to prepare alkylboronates, which are valuable and versatile synthetic intermediates. The typical boron-homologation reaction, also known as the Matteson reaction, involves formal carbenoid insertions into C-B bonds. Here we report the development of aza-Matteson reactions via carbenoid insertions into the N-B bonds of aminoboranes. By changing the leaving groups of the carbenoids and altering Lewis acid activators, selective mono- and double-methylene insertions can be realized to access various α- and β-boron-substituted tertiary amines, respectively, from common secondary amines. The derivatization of complex amine-containing bioactive molecules, diverse functionalization of the boronate products, and sequential insertions of different carbenoids have also been achieved.

Meayamycin B is currently the most potent modulator of the splicing factor 3b subunit 1 and used by dozens of research groups. However, current supply for this natural product analogue is limited because of the lengthy synthetic scheme. Here, we report a more concise, more cost-effective, and greener synthesis of this compound by developing and employing a novel asymmetric reduction of a prochiral enone to afford an allylic alcohol with high enantioselectivity. In addition to this reaction, this synthesis highlights a scalable Mukaiyama aldol reaction, Nicolaou-type epoxide opening reaction, stereoselective Corey-Chaykovsky-type reaction, and a modified Horner-Wadsworth-Emmons Z-selective olefination. We also discuss a Z-E isomerization during the α,β-unsaturated amide formation. The new synthesis of meayamycin B consists of 11 steps in the longest linear sequence and 24 total steps.
