Lewis acid-catalyzed one-pot, three-component route to chiral 3,3′-bipyrroles

(Chemical Equation Presented) 3,3′-Bipyrroles 3 could be synthesized using a double Michael addition reaction involving diaroyl acetylene 1 and the appropriate 1,3-dicarbonyls 2 using ammonium acetate as a nitrogen source. The axial chirality of bipyrrole was anticipated from the X-ray crystal structure and DFT calculations and confirmed by separating the racemates on a chiral column and subsequent CD spectra of the enantiomers. The absolute configuration of the enantiomers was achieved by theoretical CD spectra calculation using the ZINDO method.

Elemental iodine-catalyzed coupling of alkynylsilanes with acid chlorides: A facile synthesis of α,β-acetylenic ketones

Alkynylsilanes undergo coupling smoothly with acid chlorides in the presence of molecular iodine under mild reaction conditions to afford the corresponding α, β-acetylenic ketones in excellent yields in a short reaction time with high selectivity.
