资源简介:
Utilizing aldehyde-substituted vinylogous carbonates and 1,3-diketones, a simple protocol is presented for the synthesis of 2,8-dioxabicyclo[3.3.1]nonane derivatives via Knoevenagel condensation followed by a hetero-Diels–Alder reaction under green reaction conditions. The structure of a key product is unequivocally confirmed by X-ray crystallography.
