In all of these syntheses, as well as our own, reagents that had to be synthesized were employed (e.g., 15 in Scheme 3). These syntheses can often be performed once on a large scale, and the reagents are typically reacted with vastly more precious material. Therefore, in a very real sense, these steps have essentially no impact on the overall efficiency of the synthesis. The first number given for total steps does not count these steps, whereas the second number counts every step from commercially available materials.

The moderate yield of this reaction was due not to the formation of a regioisomer but rather to competitive methylalumination of the alkyne, which led to alkene products that we were unable to supress.

Attempts to perform the olefination reaction with a TBS protecting group for the C(19) alcohol were unsuccessful, and this necessitated the switch to a PMB protecting group. The side reactivity of a β-OTBS group on the aldehyde coupling partner in Julia-Kocienski olefination reactions has been explained in detail by Evans. See

The 43% yield for the conversion of 4 to 5 of course had a large impact on the overall yield. Because this step comes very near the beginning of the sequence, however, the low yield had less of an impact in terms of the loss of valuable material. In that regard, it is worth noting that the overall yield of the 19-step sequence from 5 to 2 was 12%.
