Article abstract of DOI:10.1016/0040-4039(94)85036-4

A highly stereoselective aldol reaction of the cobalt-complexed 4-methylpent-2-ynal 2 with O-silyl ketene O,S-acetal 3 provided the syn-aldol product, which was subsequently converted to (+)-bengamide E through optical resolution and the second diastereoselective aldol reaction as crucial steps.
