Synthesis of Trimethyl α-Keto Trithioorthoesters and Dimethyl α-Keto Dithioacetals by Reaction of Acyl Chlorides, Anhydrides, Thiol Esters, and N,N-Dimethylamides with [Tris(methylthio)methyl]lithium
An unprecedented enantioselective α‐functionalization of C4‐substituted N‐alkoxycarbonyl isoxazolidin‐5‐ones, readily available platforms from Meldrum's acidderivatives, by N‐sulfanylphthalimide (PhthSR) electrophiles was achieved upon an efficient phase‐transfer catalytic approach, mediated by a commercial N‐spiro quaternary ammonium catalyst. Two catalytic activities of the in situ formed R4N+Phth−

Synthetic and mechanistic studies on the antitumor antibiotics esperamicin A1 and calicheamicin .gamma.1. Oxidative functionalization of the 13-ketobicyclo[7.3.1]tridecenediyne core structure: construction of the allylic trisulfide trigger

The simple 13-ketobicyclo[7.3.1]tridecenediyne 3 corestructure of the esperamicins/calicheamicin can be readily functionalized in an oxidative manner to introduce the 1,2 double bond and 3β-oxygen substituent. The 3β-hydroxyl substituent allowed the intramolecular introduction of a nitrogen functionality at C2, but the resulting cyclic carbamate was too resistant to hydrolysis to be synthetically
