First stereoselective total synthesis of seimatopolide A
摘要:
The first stereoselective total synthesis of seimatopolide A (1) has been achieved. The key steps are Keck allylation, Sharpless asymmetric dihydroxylation, cross-, and ring-closing metathesis reactions. (C) 2012 Elsevier Ltd. All rights reserved.
A novel strategy for the chiral 2,4,5-triol moiety and its application to the synthesis of seimatopolide A and (2S,3R,5S)-(−)-2,3-dihydroxytetradecan-5-olide
摘要:
A highly stereoselective approach to the total synthesis of seimatopolide A and (25,3R,5S)-(-)-2,3-dihydroxytetradecan-5-olide is described via a common polyketide precursor by means of Prins reaction and MacMillan aminoxylation sequence. (C) 2012 Elsevier Ltd. All rights reserved.
