The C-2' absolute configrations of hydroxy esters (1) and (2) have been determined by X-ray analysis.The absolute configurations at C-15 of several compounds with the E-homoeburnane skeleton <(3)-(6)> and the relative configurations at C-14 and -15 of compound (8) have been elucidated.The dominant conformation of compounds (3)-(7) have been established on the basis of 13C n.m.r. and c.d.spectroscopic results.A new method has been elaborated for the preparation of oxime (10), a compound of importance in the synthesis of Vinca alkaloids.
