  A shortening of the reaction path can be realized by using a series of the chiral oxazaborolidinone-promoted aldol reaction with respect to the practical synthesis of the (+)-acutiphycin seco acid derivative 5. The linear strategy is based on the utilization of five aldol reactions with a sequence of silyl nucleophiles, 7, 8, 35, 10, and 11, in the presence of stoichiometric amounts of the promoter, 1 or 2. The construction of the relative configuration between the stereogenic centers is diastereoselectively controlled by the stereochemistry of the promoter used in the enantioselective aldol reaction, which is nearly independent of that of the substrate (promoter control).
