Mycothiol is comprised of N-acetylcysteine (AcCys) amide linked to 1D-myo-inosityl 2-amino-2-deoxy-alpha-D-glucopyranoside (GlcN-Ins) and is the predominant thiol found in most actinomycetes. Mycothiol S-conjugate amidase (Mca) cleaves the amide bond of mycothiol S-conjugates of a variety of alkylating agents and xenobiotics

In the presence of sulfur dioxide and an acid promoter, (-)-(1E,3Z)-2-methyl-1-((1S)-1-phenylethoxy)penta-1,3-dien-3-yl isobutyrate reacts with (Z)-3-(trimethylsilyloxy)pent-2-ene giving a silyl sulfinate intermediate that undergoes, in the presence of palladium catalyst, a desilylation and retro-ene elimination of SO(2) with formation of (-)-(1Z,2S,3R,4S)-1-ethylidene-2,4-dimethyl-5-oxo-3-((1S)-1-phenylethoxy)-heptyl isobutyrate
