The allylstannane was also prepared by an alternative synthetic route: addition of the 1,3-dithiane anion to TBS-glycidol, followed by cleavage of the TBS protecting group and acetonide formation, yielded the functionalized 1,3-dithiane, which was further lithiated and trapped with DMF. Reduction of the resultant aldehyde, followed by TBS-protection. dithiane deprutection. Wittig-olefination, and TBS- deprotection, gave an allyl alcohol, which was converted into 18 by adopting the last two reactions of step g in Scheme 2).

II-mediated couplings of iodoglucals with aldehydes proceeded smoothly to yield a diastereomeric mixture of allylic alcohols: the major product was the undesired stereoisomer. Second, addition of the 1,3-dithiane anion (THF, HMPA) of an acyclic E-ring precursor to a model aldehyde gave the undesired diastereomer as the major product.

1H NMR analysis of the crude product showed the stereoselectivity of this coupling to he greater than 7:1. The minor undesired C38 diastereomer could he converted stereospecifically into the desired isomer by oxidation with TPAP/NMO followed by Luche reduction.

The deproteclion under the specified condition in Scheme 4 was very clean (TLC analysis), hut the yield of the isolated product was only in the ranee of 20-30%. It is not yet established whether this low yield is due to a problem with isolation and/or with unidentified decomposition/side-reaclions.
