[formula: see text] In this Letter we demonstrate the viability of a highly stereoselective tandem Mannich cyclization-grammine fragmentation/addition cascade, critical for assembly of the A and F rings of penitrem D. We also explored simultaneous ex

We found that we could employ a disubstituted alkynyl halide in an Ullmann ether reaction to produce the cis-alkene intermediate 3 of the combretastatin natural products.

We report an efficient means to synthesize either enantiomer of α-unsubstituted aldol adducts in high enantiomeric excess through the use of β-keto δ-dioxolane sulfoxide 4. Through a short sequence of reactions, α-unsubstituted aldol products are

The dissociation dynamics of methoxysulfinyl radicals generated from the photodissociation of CH(3)OS(O)Cl at 248 nm is investigated using both a crossed laser-molecular beam scattering apparatus and a velocity map imaging apparatus. There is evidenc
