Hydroboration of β-acetylenic alcohols followed by NaOH/H2O2 oxidation leads to hemiacetals of γ-aldols which are easily dehydrated to 2,3-dihydrofuran compounds. The reaction gives good yields with hindered alcohols and its stereochemistry may be controlled during the organometallic synthesis of the starting alcohol.
β-炔醇的硼氢化反应,然后进行NaOH / H 2 O 2氧化,导致生成的γ-醛缩醛半缩醛容易脱水成2,3-二氢呋喃化合物。该反应在受阻醇的作用下具有良好的收率,并且可以在起始醇的有机金属合成过程中控制其立体化学。

construction of tetrahydropyrans derived from readily available 1,2-dioxines containing a tethered hydroxyl moiety is described. The reaction proceeds via a base-catalyzed rearrangement of the 1,2-dioxines to either the isomericcis or trans γ-hydroxy enones followed by intramolecular oxa-Michael addition of the tethered hydroxyl group.

A new, short, high-yielding route to 4,5-dihydro-3H-1-benzazepines has been developed based on the rhodium-catalysed hydroformylation of readily available ortho-propenylbenzeneamines; a comparison with the hydroformylation of the corresponding ortho-propenylphenols is made.
