Stereoselective Total Synthesis of Paecilomycins E and F
Autor: Nisith Bhunia, Biswanath Das
Publikováno v: Synthesis. 47:1499-1509
The stereoselective total synthesis of two bioactive resorcylic acid lactones, paecilomycins E and F has been accomplished thorough a general pathway using cis-butene-1,4-diol as the starting material. The pivotal steps of the synthesis include Sharp

One-Pot Synthesis of Pentasubstituted Pyrroles from Propargylic Alcohols, Amines, and Dialkyl Acetylenedicarboxylates; Tandem Amination, Propargylation and Cycloisomerization Catalyzed by Molecular Iodine
Autor: Biswanath Das, Nisith Bhunia
Publikováno v: Synthesis. 45:1045-1050
A multicomponent one-pot synthesis of fully substituted pyrroles has been developed by the tandem reaction of amines, dialkyl acetylenedicarboxylates, and propargylic alcohols using iodine as a catalyst. The reaction was complete in three hours and a
