Xuan, Yi-ning; Chen, Zhen-yu; Yan, Ming published the artcile< An organocatalytic cascade reaction of 2-nitrocyclohexanone and α,β-unsaturated aldehydes with unusual regioselectivity>, Name: 3-(4-Bromophenyl)acrylaldehyde, the main research area is nitrocyclohexanone aldehyde unsaturated organocatalyst conjugate addition Henry reaction; nonanone bicyclo stereoselective preparation.
An organocatalytic cascade reaction of 2-nitrocyclohexanone and α,β-unsaturated aldehydes was developed. Bicyclo[3.3.1]nonanone products, e.g., I, were obtained with good yields and excellent enantioselectivities. The reaction occurred with unusual regioselectivity. A dienolate-iminium activation mechanism was proposed. The products were transformed to eight-membered cyclic ketones, e.g., II, with high enantioselectivity.
Chemical Communications (Cambridge, United Kingdom) published new progress about Bicyclic compounds, ketones Role: SPN (Synthetic Preparation), PREP (Preparation). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Name: 3-(4-Bromophenyl)acrylaldehyde.
