Smiles/Pudovik/Phospha–Brook Cascades from Passerini–Smiles Adducts
The Passerini–Smiles reaction of aliphatic ketophosphonates affords starting materials for complex cascades triggered by a first Smiles rearrangement. The cascade showcases the power of phosphorous based transformations. Here the reversibility of the Pudovik reaction allows a further Truce–Smiles reaction enol before final Pudovik/Phosph–Brook sequence.

Polycyclic intermediates enable stereocontrolled synthesis of densely functionalized cis‐1,3‐diamine and amino alcohol carbocycles and heterocycles via structural‐to‐functional complexity transformations from low‐complexity starting material. Cis‐1,3‐functionalized carbocycles and saturated heterocycles are ubiquitous motifs in natural products ...

Dihydroquinazolinones by Titanocene‐Catalyzed Reductive Radical Addition to Quinazolinones
Tri‐ and tetracyclic dihydroquinazolinones or quinazolinones by titanocene catalysis: A highly diastereoselective and efficient reductive radical addition to quinazolinones enables an unprecedented entry to pharmaceutically relevant dihydroquinazolinones by avoiding the interception of radical intermediates prior to the slow radical addition.

ProTides for Antiviral Activity Beyond Liver Cells
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.
