Total synthesis of forskolin - Part I
Delpech, Bernard,Calvo, Daniel,Lett, Robert
, p. 1015 - 1018 (2007/10/03)
A new total synthesis of forskolin 1 has been achieved and this note describes the synthesis of the transfused enone 18 as a key-intermediate. Key steps are: 1) the intramolecular Diels-Alder reaction of 17 to afford the tricyclic lactone 8 (48-56%); 2) a
