Rapid, two-pot procedure for the synthesis of dihydropyridinones; total synthesis of aza-goniothalamin (Beilstein Journal of Organic Chemistry)

Abstract A fast, protecting-group-free synthesis of dihydropyridinones has been developed. Starting from commercially available aldehydes, a novel one-pot amidoallylation gave access to diene compounds in good yields. Ring-closing metathesis conditions were then employed to produce the target dihydropyridinones efficiently and in high yields. Beilstein J. Org. Chem. 2020, 16, 135–139. doi:10.3762/bjoc.16.15
