Abstract
A benzothiazolyl TMS-propargylic sulfone was subjected to one-pot Julia olefinations with a variety of aliphatic and aromatic aldehydes. Predominant Z -selectivity up to 98:2 and good chemical yields were obtained in a facile route to the desired Z -1,3-enyne moieties.
Key words
enynes - olefination - aldehydes - propargylic sulfones - natural products

20 Preparation of aldehyde 8f , starting from the alcohol 9 (Scheme
[3 9 was prepared according to: Bonini, C.; Chiummiento, L.; Videtta, V.; Colobert, F.; Solladié, G., manuscript in preparation.
21 No β-elimination product was observed for aldehyde 8e . Moreover, the optical rotation for the unreacted aldehyde 8f shows the same the value of the starting aldehyde, thus indicating that no epimerization reaction occurs.
