8-甲基-2-亚甲基-1,4,6,9-四氧杂螺[4.4]壬烷的合成与结构
摘要:
By reacting propylene carbonate with epichlorohydrin 8-methyl-2-chloromethyl-1,4,6,9-tetraoxaspiro[4.4]nonane was obtained that afforded 8-methyl-2-methylene-1,4,6,9-tetraoxaspiro[4.4]nonane on dehydrochlorination. The spirocompounds synthesized are composed of stereoisomers mixtures containing: cis,syn, cis,anti-, trans,syn-, trans,anti-isomers and cis,syn-, cis,anti-isomers, respectively. These isomers are distinguished by a different orientation of substituents in positions 2 and 8 with respect to two five-membered rings.
