Until the early 1970s, nearly all filter synthesis techniques were based on the extraction of electrical elements (lumped capacitors and inductors, transmission line lengths) from the polynomials that ...

Synthesis of unavailable imaging modalities from available ones can generate modality-specific complementary information and enable multi-modality based medical images diagnosis or treatment. Existing ...

We report an efficient and stereoselective synthesis of tetrasubstituted alkenes through palladium-catalyzed Suzuki–Miyaura coupling of arylboronate esters with O-alkenyl oxyphosphonium salts. These ...

A concise enantioselective total synthesis of 4′-ethynyl-2-fluoro-2′-deoxyadenosine (EFdA), an extremely potent anti-HIV agent, has been accomplished from (R)-glyceraldehyde acetonide in 18% overall ...
