Janne E Tønder et al.
Organic & biomolecular chemistry, 2(10), 1447-1455 (2004-05-12)
Copper mediated allylic substitutions and conjugate additions to geranyl, cinnamyl and allylic indole compounds have been investigated with the aim of finding a method for the creation of the all-carbon quaternary centre present in the natural product lyngbyatoxin A. Reaction
M Wältermann et al.
Microbiology (Reading, England), 146 ( Pt 5), 1143-1149 (2000-06-01)
The triacylglycerol (TAG)-accumulating, hydrocarbon-degrading bacterium Rhodococcus opacus strain PD630 and chemically induced storage-deficient mutants derived from this strain were investigated for their capability to accumulate storage lipids in the cytoplasm during cultivation under nitrogen-limiting conditions. Acylglycerols were analysed by matrix-associated
T Nishiyama et al.
Chemical & pharmaceutical bulletin, 48(12), 1999-2002 (2001-01-06)
The direct alpha-bromination of various ketones using trifluoromethanesulfonic anhydride and Grignard reagent or magnesium bromide in ether gave the corresponding alpha-bromo ketones in moderate to good yields under mild reaction conditions.
F Turon et al.
Lipids, 37(8), 817-821 (2002-10-10)
An analytical procedure was developed for regiodistribution analysis of TAG using alpha-MAG prepared by an ethyl magnesium bromide deacylation. In the present communication, the deacylation procedure is shown to lead to representative alpha-MAG, allowing the composition of the native TAG
Yasuhiro Ando et al.
Journal of oleo science, 57(8), 459-462 (2008-07-16)
This paper presents a procedure for preparation of a Grignard reagent, ethyl magnesium bromide, used for partial deacylation of triacylglycerols (TAG) in their regiospecific analysis. Magnesium turnings were reacted with ethereal solution of bromoethane in a screw-capped test tube to
Yuichi Kobayashi et al.
Organic letters, 7(2), 183-186 (2005-01-14)
[Reaction: see text] Low regioselectivity of RMgBr (R = aryl, alkenyl) in the CuCN-catalyzed reaction with 4-cyclopentene-1,3-diol monoacetate is improved by addition of LiCl or MgCl2 to a similar extent as previously obtained with RMgCl (>90:10). The limitation encountered in
R G Xie et al.
Steroids, 55(11), 488-490 (1990-11-01)
The reaction of ethyl magnesium bromide and 17 alpha-ethynylestradiol with formaldehyde in the presence of triethyl phosphate or hexamethylphosphoramide gave the 2- and 4-formyl-17 alpha-ethynylestradiol in high yield. Treatment of the formyl derivatives with an alkaline solution of hydrogen peroxide
