[GRAPHICS]An improved procedure for the resolution of 4-trimethylsilyl-3-butyn-2-ol has been developed. The mesylate derivatives of the resolved alcohols have been found to undergo highly enantio-, regio-, and diastereoselective additions to aldehydes, leading to homopropargylic alcohol adducts.

Additions of chiral allenylzinc and indium reagents to N-Boc alaninal were examined as a possible route to a C20-C26 segment of superstolide A. Allenylzinc reagents, prepared in situ by palladiozincation of (R)- and (S)-5-pivalyloxy-3-butyn-2-ol mesylate, showed excellent reagent control to afford the anti,syn and anti,anti diastereomers as the nearly exclusive adducts.
