Gold(I)-catalyzed synthesis of functionalized cyclopentadienes.
mechanistic pathways: a concerted rearrangement (path a) involving direct addition of the olefin on the epoxide or a stepwise mechanism (path b) through a Nazarov cyclization of an oxypentadienyl cation (2, X=O ). The regioselectivity of the cyclization is dictated by donation of the oxyanion into the resulting cation leading to the formation of a ketone. Recently, stabilization of developing p...
متن کاملOne-pot Synthesis and Characterization of Highly Functionalized Thiazoles
A facile and efficient one-pot three-step process for the synthesis of 5-acetyl-2-imino-4-methylthiazoles via the cyclocondensation of 3-thiocyanatoacetylacetone with various hydrazine or hydrazide derivatives in EtOH has been developed. 3-Thiocyanatoacetylacetone itself has been synthesized as the intermediate from substitution reaction of thiocyanate with 3-chloroacetylacetone. B...
متن کاملSynthesis of highly functionalized fluorinated cispentacin derivatives.
Fluorinated highly functionalized cispentacin derivatives were synthetised starting from an unsaturated bicyclic β-lactam through C=C bond functionalization via the dipolar cycloaddition of a nitrile oxide, isoxazoline opening, and fluorination by OH/F exchange.
