The [2, 3]-sigmatropic rearrangement of allylic sulfoxides to allylic sulfenates is a reversible
process, generally shifted toward the sulfoxide. In the presence of thiophiles, the sulfenate is …

Rearrangements of sulfoxides and sulfones in the total synthesis of natural compounds{ Page 1
Abstract. Data on applications of the most important rearrangements of sulfoxides and sulfones …

The formation of the trisubstituted cycloalkene 7 by RCM of diene 5 proceeds via the acyclic
dimer 6, thus demonstrating the ready reversibility of olefin metathesis if catalyzed by …

A pathotype of Drechslera avenae (Eidam) Scharif exhibited host‐specificity, being
pathogenic to Avena sterilis L but not to a number of related or unrelated species tested. In …

Conclusion In summary, this review article has illustrated the application of three-component
coupling reactions, core expansion and dimerization strategies that have greatly simplified …

Abstract Pyrenophorol (1) and (–)‐dihydropyrenophorin (3), two known macrodiolides, were
isolated together with four new analogues (2, 4–6) and three ring‐opened derivatives (7–9) …

A secondary metabolite was isolated from cultures of a Drechslera avenae pathotype with
host specificity to Avena sterilis and identified as the macrodiolide (8 R, 16 R)-(−) …

The biochemical mode of action of (5 S, 8 R, 13 S, 16 R)-(−)-pyrenophorol isolated from a
Drechslera avenae pathotype was investigated by using metabolic fingerprinting. 1H NMR …

The high reactivity of the P-lactone group severely limits the number of successful
lactonisation techniques available for its formation. Schick et aZ. have recently demonstrated …

Decarestrictine L was prepared via intramolecular 1, 4-addition of the oxy-anion, derived
from trialkylsilyl ether with Bu4NF, to the internal γ-hydroxy enone functionality, formed by …
