Short synthesis of functionalized pentalongin derivatives using pyridinium ylid chemistry
-
Add time:09/06/2019 Source:sciencedirect.com
3-Substituted pentalongin derivatives possessing an acetal function at C-1 were synthesized by cyclization of acylmethylnaphthoquinones. The latter naphthoquinones were prepared starting from 2-dioxolanylnaphthoquinone by means of both a stoichiometric and a catalytic method deploying various pyridinium ylids.
