Organoaluminium induced ring-opening of epoxypyranosides. V. Formal total synthesis of antimycin A3 and synthesis of (+)-blastmycinone

Epoxide ring-opening of the benzyl 2,3-anhydro-α-L-ribopyranoside 6 with lithium butynyl(trimethyl)aluminate followed by functional group interconversions gave the dihydroxy thioacetal 11, which was regio-selectively acylated with an L-threonine derivativ
