Convenient Continuous Flow Synthesis of N-Methyl Secondary Amines from Alkyl Mesylates and Epoxides
Lebel, Hélène,Mathieu, Gary,Patel, Heena
, p. 2157 - 2168 (2020/11/23)
The first continuous flow process was developed to synthesize N-methyl secondary amines from alkyl mesylates and epoxides via a nucleophilic substitution using aqueous methylamine. A variety of N-methyl secondary amines were produced in good to excellent yields, including a number of bioactive compounds or their precursors. Up to 10.6 g (88% yield) of an N-methyl secondary amine was produced in 140 min process time. The amination procedure included an in-line workup, and the starting mesylate material was also produced in continuous flow from the corresponding alcohol. Finally, an in-line process combining the mesylate synthesis and nucleophilic substitution was developed.

The multiple roles of protein kinase D (PKD) in various cancer hallmarks have been repeatedly reported. Therefore, the search for novel PKD inhibitors and their evaluation as antitumor agents has gained considerable attention. In this work, novel pyrazolo[3,4-d]pyrimidine based pan-PKD inhibitors with structural variety at position 1 were synthesized and evaluated for biological activity. Starting from 3-IN-PP1, a known PKD inhibitor with IC50 values in the range of 94–108 nM, compound 17m was identified with an improved biochemical inhibitory activity against PKD (IC50 = 17–35 nM). Subsequent cellular assays demonstrated that 3-IN-PP1 and 17m inhibited PKD-dependent cortactin phosphorylation. Furthermore, 3-IN-PP1 displayed potent anti-proliferative activity against PANC-1 cells. Finally, a screening against different cancer cell lines demonstrated that 3-IN-PP1 is a potent and versatile antitumoral agent.

One-pot preparation of Julia-Kocienski sulfides and sulfones from alcohols
Ando, Kaori,Hattori, Junichiro
, (2019/08/12)
A method for one-pot preparation of Julia-Kocienski sulfides and sulfones from alcohols and thiols is reported. A variety of primary alcohols were converted to the corresponding mesylates by methansulfonyl chloride and triethylamine in THF. After the reaction is complete, thiol (1 or 10) and either NaH or t-BuOK were added. The Julia-Kocienski sulfides 3, 9 and 11 were prepared by one-pot two steps procedure from alcohols in 76–96% yields (16 examples). Furthermore, after the sulfide formation, the reaction mixture was neutralized by p-toluenesulfonic acid and treated with H2O2 and ammonium molybdate in EtOH to give the Julia-Kocienski sulfones 4 in good yields except for trans-2-hexen-1-ol.

Amphipathic cationic peptoids (N-substituted glycine oligomers) represent a promising class of antimicrobial peptide mimics. The aim of this study is to explore the potential of the triazolium group as a cationic moiety and helix inducer to develop potent antimicrobial helical peptoids. Herein we report the first solid-phase synthesis of peptoid oligomers incorporating 1,2,3-triazolium-type side chains and their evaluation against Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus. Several triazolium-based oligomers, even of short length, selectively kill bacteria over mammalian cells. SEM visualization of S. aureus cells treated with a dodecamer and a hexamer reveals severe cell membrane damage and suggests that the longer oligomer acts by pore formation.

Paragraph 0151; 0208-0210, (2016/10/08)
The invention relates to a hydroxylamine synthesis method. The hydroxylamine synthesis method comprises the following steps: (A) enabling alcohol to react with alkyl sulfonyl halide in the presence of an acid-binding agent to obtain sulphonate; (B) enabling the obtained sulphonate in the step (A) to react with N-hydroxycyclodiimide in the presence of alkali to generate alkylate of the N-hydroxycyclodiimide; and (C) enabling the alkylate obtained in the step (B) to react with an aminolysis reagent or a hydrazinolysis reagent to obtain the hydroxylamine. The method is high in yield and suitable for large-scale industrial hydroxylamine synthesis.
