The development of Karplus‐type formulas that relate the NMR coupling constants of
carbohydrates and related ma olecules to the dihedral angle between the coupled nuclei is …

Two sulfated diterpene glycosides featuring a highly substituted and sterically encumbered
cyclopropane ring have been isolated from the marine red alga Peyssonnelia sp …

A modular approach toward the synthesis of all possible trimer repeating units of the type 1
capsular polysaccharide of Streptococcus pneumonia, Sp1, is described. This zwitterionic …

Three members of a new class of ascorbic acid-adduct indole alkaloids (1–3), a new
prenylated indole alkaloid (4), and five known compounds (5–9) were isolated from the …

Paraphaeoketones A–C (1–3) were isolated from the culture broth of Paraphaeosphaeria
sp. KT4192. Their structures and relative configurations were determined using …

Dioxaphosphabicyclo [2.2. 2] octanes (L1–L4) have been prepared in a one-pot reaction
from tris (hydroxymethyl) phosphine and various α, β-unsaturated ketones. The non-volatile …

Deoxy‐β‐ido‐heptopyranosides are challenging glycosides to synthesize due to their
unusual 6‐deoxy‐heptose backbone, rare ido‐configuration and most importantly, the β‐1, 2 …

The reaction of NH-indazoles with formaldehyde in aqueous hydrochloric acid has been
experimentally studied by solution and solid-state nuclear magnetic resonance (NMR) and …

Divergent pathways are disclosed in the activation of 2-O-benzyl-1-hydroxy sugars by a
reagent combination of CBr4 and Ph3P, all of which afford one-pot α-glycosylation methods …

We report the synthesis of a mixed methyl-and hydro-substituted cyclosilane (1) possessing
cis/trans stereoisomerism. Each diastereomer of 1 possesses distinct symmetry elements …
