Enantiospecific synthesis of (+)-hyacinthacine A2
Dewi-Wülfing, Purnama,Blechert, Siegfried
, p. 1852 - 1856 (2007/10/03)
We report an efficient synthesis of (+)-hyacinthacine A2 in six steps from (S)-N-Cbz-vinylgylcine. The key strategies were the olefin cross metathesis (CM), Sharpless asymmetric dihydroxylation, and a sequential double reductive cyclization. Wi
