Abstract
The natural compound dendocarbin A, C15H22O3, is a sesquiterpene lactone isolated for the first time from Drimys winteri for var chilensis. The compound crystallizes in the orthorhombic space group P212121 and its X-ray crystal structure confirmed the S/R character of the chiral centres at C-5/C-10 and C-9/C-11, respectively. The α–OH group at C-11 was found to be involved in intermolecular hydrogen bonding, defining chains along the <100> 21 screw axis.
