    • Although the yield of this step (65%) is somewhat lower to the calculated global yield of the two separated steps (86%), the success of the pseudo-domino sequence represents an interesting goal from the conceptual (as it validates the feasibility of the principle) as well as practical viewpoint (as it saves a work-up procedure and a purification step).
