Synthesis of new allocolchicinoids with seven- and eight-membered B-rings by enyne ring-closing metathesis

Total syntheses of allocolchicines 4 and 5, with the ester functionality in the C-ring at the C10 or C11 positions, is reported. An asymmetric synthesis of (7S)-allocolchicine 5 is also described. The main features included the elaboration of a common int

Synthesis of allocolchicines using sequential ring-closing enyne metathesis - Diels - Alder reactions

New allocolchinoids having functionality in the C ring at position C10 or C11 have been synthesized using the enyne ring-closing metathesis (RCM) reaction for construction of the seven-membered ring and a Diels-Alder-aromatization sequence for the elabora
