Oxidation of ketone acetals by hydride transfer
Trityl fluoroborate is a useful reagent for the deacetalisation of ketone acetals, the glycol function being thereby smoothly oxidised to an α-ketol; the reaction has synthetic application especiallyExpand
Geometry of 1,2-dihydroxy-1,2-disulphonates
Abstract An evaluation of the probability of hydrogen bonding between sulphonate and hydroxyl groups on adjacent carbon atoms of 1,2-dihydroxy-1,2-disulphonates is reported. Using published bondExpand
Modifying effect of ultrasound upon the electrochemical oxidation of cyclohexanecarboxylate
The electrochemical oxidation of cyclohexanecarboxylate, performed under conditions which normally produce equivalence of both one-electron and two-electron pathways, exhibits a marked predominanceExpand

  • 6 August 1973
Of the five T7 early mRNAs, only two were found to terminate in a guanosine triphosphate residue at the 5′-terminus, and the amount of pppGp found indicates that several copies of the smaller RNA may be present. Expand
The Crystal Structure of Acifluorfen {5-[2-Chloro-4-(trifluoromethyl)-phenoxy]-2-nitrobenzoic Acid}
The crystal structure of the herbicide acifluorfen (5-[(2-chloro-4-trifluoromethyl)]phenoxy-2- nitrobenzoic acid] has been determined by X-ray diffraction and refined to a residual of 0.051for 1124Expand
Two crystal polymorphs of a flavonoid from Melicope ellyrana.
The crystal structure determinations of two crystalline components of the hexane extract of the fruit of the indigenous Australian tree Melicope ellyrana have shown them to be polymorphs of the sameExpand
Synthesis and Solid-State Structure of the Unsymmetrical Squaraine Dye 2-[4-(Dibutylamino)-2-hydroxyphenyl]-4-[4-(dibutylamino)phenyl]-cyclobutenebis(ylium)-1,3-diolate
The synthesis of an unsymmetrical squaraine dye, 2-[4-( dibutylamino )-2-hydroxyphenyl]-4-[4-( dibutylamino )phenyl] cyclobutenebis ( ylium )-1,3-diolate, has been achieved via a cross condensationExpand
Steric acceleration of an uncatalysed ene reaction at room temperature.
The bulky trityl steric buttress is used to effect an intramolecular, uncatalysed ene reaction that operates at room temperature, whilst smaller buttresses require heat.
Experiments of the synthesis of tetracycline. Part V. Photocyclisation of ring B
The ethylene acetal of 4-(2-formylbenzyl)-2phenylnaphtho[1,8-bc]furan-5-one (III; XY = O) has been cyclised under acid-catalysed photolytic conditions toExpand
