Gold(I)-Catalyzed 1,3-Carbofunctionalizations of Anthranils with Vinyl Propargyl Esters To Yield 1,3-Dihydrobenzo[c]-isoxazoles
摘要:
This work describes gold-catalyzed 1,3-carbofunctionalizations of anthranils with vinyl propargyl esters to form 1,3-dihydrobenzo[c]-isoxazoles. Excellent diastereoselectivity has been achieved to yield products containing three stereogenic carbons. These new catalytic reactions are operable with anthranils and vinyl propargyl esters over a wide scope, further manifesting the synthetic utility.

A novel, one-pot ring-expansion procedure was developed using Me3S(O)I, NaH, and Sc(OTf)3. The scope and limitations were briefly examined, and a tentative mechanism was proposed. Application of the methodology to known cyclobutanone 1 provided the corresponding cyclopentanone, which was successfully advanced to (+)-carbovir and (+)-aristeromycin.
diastereoselective [3,3]-sigmatropic rearrangement. Mechanistic investigations revealed that the [3,3]-sigmatropic rearrangement proceeds with transfer of chirality. These inspire a photocatalyzed olefin isomerization of the aldol condensation product leading to a highly diastereoselective [3,3]-sigmatropic rearrangement to furnish the α-homoallylation of cyclic enones. Importantly, this photocatalyzed
