Reaction of the cyclic 1, 3-dicarboxylic acid derivatives (1), (2) and (3) with (R)- or (S)-citronellal (4/5) gives the enantiomeric tricyclic dihydropyrans (10), (11), (12) and (13), probably via a 100% stereocontrolled intramolecular cycloaddition.
环状1、3-二羧酸衍生物(1),(2)和(3)与(R)-或(S)-香茅醛(4/5)反应,得到对映体三环二氢吡喃(10),(11) ,(12)和(13),可能是通过100%立体控制的分子内环加成反应。
