Enantiospecific synthesis of [7R,6S,5S,4R]-triacetoxy-(−)-goniotriol
摘要:
A short and efficient synthesis of [7R,6S,5S,4R]-triacetoxy-(-)-goniotriol starting form D-glucose is described. A sequence of ring closing metathesis (RCM) followed by a PCC oxidation was used to construct the core six-membered alpha,beta-unsaturated lactone moiety. (C) 2002 Elsevier Science Ltd.

RCM/PCC oxidation strategy for synthesis of functionalized cyclic α,β-unsaturated lactones: synthesis of (+)-triacetoxygoniotriol and its diastereomers
摘要:
A novel methodology leading to the synthesis of (+)-triacetoxygoniotriol 2 from D-glucose is described. Construction of the core six-membered alpha, beta-unsaturated lactone moiety involved ring closing metathesis (RCM) followed by a PCC oxidation. Later exploiting the pseudo-symmetry of D-glucose three other diastereomers of triacetoxygoniotriol were synthesized using the developed methodology. (c) 2006 Elsevier Ltd. All rights reserved.
