| Title: | Intramolecular (4 + 3) cycloadditions of nitrogen-tethered epoxy enosilanes for the synthesis of heteropolycycles | Authors: | He, J Lam, SM Ng, JPL Wong, WT Chiu, P |
Issue Date: | Aug-2019 | Source: | Chinese chemical letters, Aug. 2019, v. 30, no. 8, p. 1523-1526 | Abstract: | Furans bearing epoxy enolsilane units via a tether that incorporates a nitrogen heteroatom, undergo intramolecular (4 + 3) cycloadditions to generate bis-heteroatomic polycyclic adducts having piperidine moieties in their frameworks. The cycloadducts, ultimately derived from furfural, a renewal chemical feedstock, are obtained with up to 4:1 dr and with ee retained from the epoxide. | Keywords: | (4 + 3) cycloaddition Epoxides Furan Heterocycles Intramolecular Piperidine Polycyclic compounds |
