Confinement-Controlled, Either syn- or anti-Selective Catalytic Asymmetric Mukaiyama Aldolizations of Propionaldehyde Enolsilanes.
Amatov T, Tsuji N, Maji R, Schreyer L, Zhou H, Leutzsch M, List B. Amatov T, et al. J Am Chem Soc. 2021 Sep 15;143(36):14475-14481. doi: 10.1021/jacs.1c07447. Epub 2021 Aug 26. J Am Chem Soc. 2021. PMID: 34436899 Free PMC article.
Here we report two highly enantioselective and diastereoselective catalytic Mukaiyama aldol reactions of the TBS- or TES- enolsilanes of propionaldehyde with aromatic aldehydes. Our reactions directly deliver valuable silyl protected propionaldehyde aldols in a cata …

Methods for determination of aldehydic lipid peroxidation products.
Esterbauer H, Zollner H. Esterbauer H, et al. Free Radic Biol Med. 1989;7(2):197-203. doi: 10.1016/0891-5849(89)90015-4. Free Radic Biol Med. 1989. PMID: 2680787 Review.
Several methods based on HPLC or GC-MS have been developed to qualitatively and quantitatively measure the aldehydes in tissues, cells and cell fractions exposed to various pro-oxidative stimuli. 4-Hydroxynonenal, hexanal and propanal are, besides malonaldehyde, the most a …

2,3-Dibromo-3-(5-nitro-2-fur-yl)-1-phenyl-propan-1-one.
Shahani T, Fun HK, Nithinchandra, Kalluraya B. Shahani T, et al. Acta Crystallogr Sect E Struct Rep Online. 2011 Feb 2;67(Pt 3):o546. doi: 10.1107/S1600536811003552. Acta Crystallogr Sect E Struct Rep Online. 2011. PMID: 21522313 Free PMC article.
In the title compound, C(13)H(9)Br(2)NO(4), the phenyl and 2-nitro-furan rings are linked by a 2,3-dibromo-propanal group, six atoms of which, including a furyl C atom, are disordered over two positions with a site-occupancy ratio of 0.733 (11):0.267 (11). ...

Retention of propanal and diacetyl in experimental resins.
Peutzfeldt A. Peutzfeldt A. Acta Odontol Scand. 1997 Apr;55(2):94-100. doi: 10.3109/00016359709115399. Acta Odontol Scand. 1997. PMID: 9176656
At low contents of propanal or diacetyl, M infinity 1 remained unchanged as compared with the control resins without additive. ...In resins based on BisGMA and TEGDMA, propanal was retained to a lesser extent than diacetyl. In resins based on UEDMA and HEMA, prop …

Total synthesis of (+)-epilupinine via an intramolecular nitrile oxide-alkene cycloaddition.
Su D, Wang X, Shao C, Xu J, Zhu R, Hu Y. Su D, et al. J Org Chem. 2011 Jan 7;76(1):188-94. doi: 10.1021/jo101910r. Epub 2010 Dec 1. J Org Chem. 2011. PMID: 21121617
We found that it was an extremely difficult task to prepare the key intermediates (R)-N-(3-nitropropyl)-2-vinylpiperidine or (R)-(2-vinylpiperid-1-yl)propanal by routine methods. Thus, by using Fukuyama's oxime synthesis, a general method was developed for highly efficient …
