, p. 795 - 799 (2015)
A racemic cis/trans mixture of 5-hexyl-4-methyl-γ-butyrolactone was easily synthesized from 1-iodoheptane in four steps with inexpensive and readily available reagents. Our new synthesis method can be potentially employed for mass production of the 4-methyl-5-hexyl-γ-butyrolactone as well as other poly-alkyl substituted γ-butyrolactones.

An efficient and experimentally straightforward method for the stereoselective synthesis of a variety of β-nitro-α-amino carboxylic acids via aza-Henry (nitro-Mannich) reaction of aldimines is disclosed, yielding either anti- or a rarely reported syn-configuration. The reaction operates directly on free glyoxylic acid and generates imine species in situ. Crystallization-controlled diastereoselectivity enables isolation of the target compounds in high enantio- and diastereomeric purities by a simple filtration.
Henry reaction of fluorinated nitro compounds
Hu, Huawei,Huang, Yangen,Guo, Yong
experimental part, p. 108 - 114 (2012/02/05)
The Henry (nitroaldol) reaction of fluorinated nitro compounds with various aromatic aldehydes and a fluorinated aliphatic aldehyde to give β-fluoro-β-nitroalcohols which bearing a fluorinated quaternary carbon center was reported. The relative configuration of the major diastereoisomer of 2-fluoro-2-nitro-1-(4-nitrophenyl)-3-phenylpropanol (5bf) was determined by X-ray single crystal analysis.
