The total synthesis of 1-oxygenated eudesmane sesquiterpenes : (±) dihydroreynosin and (±) 1-oxocostic acid
The total synthesis of (±) dihydroreynosin 1 and of (±) 1-oxocostic acid 2 (R = H) are illustrative examples for a short entry into 1-oxygenated eudesmanes via an easily accessible key intermediate 7
The total synthesis of 1-oxygenated eudesmanolides
A route towards I-oxygenated eudesmanolides, via a (2+2) photocycloaddition reaction for constructing the decalin framework is described. The following natural substances have been synthesized. (=)-dihydroreynosin (1), (±)-1- oxo-dihydronmagnolialide (2), (±)-maritimin (3), (±)-dihydromagnolialide (4), (±)-magnolialide (5), (±)-dihydrosantamarine (6). Also a synthesis of (±)--santonin (7) is presented
Diterpene total synthesis : an improved stereoselective route to (±)-3,4,5,5a,7,8,8aα,8bα-octahydro-2aα,5aβ-dimethyl-2H-naphto-|1,8-bc|furan-2,6-(2aH)-dione
The synthesis of the title compound 13, via a photochemical (π2 + π2) annellation procedure and a highly stereo-selective hydrocyanation reaction, is described
