d-(+)-lactate and d-glucose, for neomethynolide, and for novamethynolide, respectively. The keysteps in synthesis of neomethynolide and novamethynolide, which are aglycones for neomethymycin and novamethymycin, respectively, were asymmetric aldol reactions, Yamaguchi esterification, and ring-closingmetathesis using Grubbs’ second generation catalyst. Finally, the coupling of agylcones with the corresponding
