5 days ago · General procedure A for the synthesis of DHPIQs. To a solution of 1 15, 35, 36 (20 mg, 0.087 mmol, 1 equiv) in MeCN (1 mL) was added corresponding 1a (2 equiv), NaI (0.5 equiv), and DIPEA (2 equiv) at rt. The resulting mixture was stirred under reflux for 12 h. The reaction was quenched with water and extracted with EtOAc (2 × 20 mL).
1 day ago · The lack of a direct route to bicyclo[1.1.1]pentyllithium or Grignard reagents leaves radical addition of P–H bonds across the reactive C–C bond of [1.1.1]propellane as the most suitable route for bicyclo[1.1.1]pentyl phosphine synthesis. Indeed, our synthesis of PBcp 3 relied on the radical alkylation of PH 3. Adapting this route to an ...
3 days ago · Viruses are a real threat to every organism at any stage of life leading to extensive infections and casualties. N-heterocycles can affect the viral life cycle at many points, including viral entrance into host cells, viral genome replication, and the production of novel viral species. Certain N-heterocycles can also stimulate the host’s immune system, producing antiviral cytokines and ...

4 days ago · After synthesis, T(SH) 2 runs within the cytosol to actively reduce disulfides in proteins (RS2) like thioredoxin, tryparedoxin, glutathione disulfide, and dehydroascorbate . Upon reduction of dehydroascorbate, ascorbate is used as substrate for ascorbate-dependent heme-peroxidase (APx), located on the endoplasmic reticulum, which provides ...
6 days ago · Definition: Mapping reviews are focused on a visual synthesis of the data and are question based rather than topic based like the scoping review. When to use: When there is an abundance and a diversity of research, as a first step to a systematic review, or to identify gaps in a topic area.
6 days ago · 6. Other digital synths: FM and wavetables. Besides virtual-analogue and sample-based synthesis, there are several other digital synthesis methods, the most popular being FM and wavetable synthesis. FM synthesis had its breakthrough in the 1980s with the famous Yamaha DX7 – one of the best-selling synths of all time.
