Enantioselective Synthesis of Putative Lipiarmycin Aglycon Related to Fidaxomicin/Tiacumicin B

An enantioselective synthesis of a putative lipiarmycin aglycon was accomplished and features: 1) Brown’s enantioselective alkoxyallylboration and allylation of aldehydes, 2) chain elongation by iterative Horner–Wadsworth– Emmons olefination, 3) Evans aldol reaction and 4) an enediene ring-closing metathesis. A neighboring-group-assisted chemoselective reductive desilylation was uncovered in this study and was instrumental to the realization of the present synthesis.
