Raghavan, Sadagopan published the artcileA short convergent synthesis of the [3.2.1]dioxabicyclooctane subunit of sorangicin A via regioselective epoxide opening, Name: (+)-B-Methoxydiisopinocampheylborane, the publication is Tetrahedron (2018), 74(10), 1071-1077, database is CAplus.
In this paper, we disclose the synthesis of the dioxabicyclo[3.2.1]octane subunit (I) of the potent antibiotic sorangicin A. The synthesis was achieved in a convergent manner in 8 steps. Regio- and stereoselective intermol. epoxide opening, ring-closing metathesis and iodo-etherification are key steps. cis-2-Butene diol has been employed as a common staring material.
