Synthetic Studies towards Pectenotoxin-2: Synthesis of the Nonanomeric 10-epi-ABCDE Ring Segment by Kinetic Spiroketalization

Autor: Petri M. Pihko, A. Piisola, K. Syam Krishnan, Jatta E. Aho

Publikováno v: European Journal of Organic Chemistry. 2011(9):1682-1694

The synthesis of the nonanomeric 10-epi-ABCDE ring system of pectenotoxin-2 has been achieved by using a kinetic spiroketalization reaction. The synthesis of the spiroketalization precursor was achieved through a cross-metathesis/hydro-genation seque

Synthetic Studies Toward Pectenotoxin 2. Part I. Stereocontrolled Access to the C10−C22 Fragment

Autor: Jatta E. Aho, Elina Salomäki, Kari Rissanen, Petri M. Pihko

Publikováno v: Organic Letters. 10:4179-4182

A highly stereocontrolled and efficient synthesis for a fully functionalized C 10-C 22 fragment of pectenotoxin 2 is described using a convergent sequence involving a stereoselective methylation of beta-hydroxyketone as a key step.

Access to Both Anomers of Pectenotoxin Spiroketals by Kinetic Spiroketalization

Autor: Petri M. Pihko, Jatta E. Aho

Publikováno v: Organic Letters. 6:3849-3852

[structure: see text] A concise synthesis of both AB ring spiroisomers of the pectenotoxins is described. The nonanomeric AB spiroketal ring system of the pectenotoxins-1, -2, -3, and -6 is formed under very mild, kinetic spiroketalization conditions

Assessment of interstitial water content of articular cartilage with T1 relaxation

Autor: Jukka S. Jurvelin, Miika T. Nieminen, Jatta E. Berberat, Mikko J. Nissi

Publikováno v: Magnetic resonance imaging. 27(5)

The interstitial water content typically increases in the early degeneration of articular cartilage. Previously, T(2) relaxation has been related to water content, yet it is known to be strongly affected by the collagen orientation. Articular cartila
