Glucose numbering

Displays glucose numbers Displays directional trends Every 1 min Yes, always has directional and rate of change arrow. Can view 2, 4, 6, 12, or 24 h glucose graph. Can go back 28 days... 

Homodromic cycles are indicated by circulator arrows with one head, antidromic cycles by arrows with two heads. Atom designation, 26 means 0(2) of glucose number 6... 

Fig. 18.13 a, b. Shown are hydrogen-bond patterns occurring in the crystal structure of / -cyclodextrin 11H20 at 120 K. Because the total scheme is too complicated to be shown in one picture, it is broken up into two different schemes. In these, water molecules are denoted by W, and hydroxyl groups by two numbers, e.g., 64 means 0(6)4, hydroxyl 0(6) of glucose number 4 in the yff-cyclodextrin macrocycle, a, Hydrogen-bonding details for flip-flop... 

A second synthesis that involves the oxidation of glucose at C6, reduction at Cl, and then oxidation at C5 (glucose numbering) is shown... 

Diels-Alder reaction between a glucose-derived enone and butadiene, followed by Ferrier rearrangement, gave (8) (glucose numbering shown), which corresponds to the AB-ring stereochemistry... 

The total synthesis of the 16-membered macrodiolide elaiophilin has been accomplished by a route which involved as a key step the reaction of a boron enolate of (47), derived from glucose (numbers... 

Fig. 1. Chemical structure of the a-cyclodextrin molecule. In the text, atoms will be numbered as shown and glucose numbers appear as additional indices, e.g. C(2) 1 means carbon atom C(2) of...

Deviations of atoms from L.S. plane Glucose number Adduct of a-cyclodextrin with Average values... 

Fig. 8c. A space filling plot of the a-cyclodextrin molecule as found in the krypton adduct, viewed from the 0(2), 0(3) side, hydroxyl protons not drawn. Van der Waals radii are H=-1.2 A, 0=1.4 A [23]. 0(2), 0(3) atoms are indicated by heavy lines, 0(4) atoms by filled circles and hydrogen atoms by light lines. The C(3)—H atoms are numbered according to the glucose numbering in Figure 8a. Averaged diagonal van der Waals distances are ...

A segment of the mstrine toxin debromoaplysiatoxin has been prepared from D-glucose as outlined in Scheme carbons 1 and 2 (glucose numbers) and 0-2 of intermediate (30) were then incorporated into the complete macrodiolide of 3-deojsydebromoaplysiatoxln by combination with two other tartrate-derived fragments.28 TS0-CH2... 

Another report describes the conversion of methyl 3-azido-4,6-0-benzylidene-2,3-dideoxy-o(-D-glucopyranoside to the -lactam (15) (glucose numbering), another precursor for thienamycin. In this... 

S,4S)-4-Methylheptan-3-ol (41)(glucose numbering), a pheromone component of the smaller European elm bark beetle, has been prepared conventionally from D-glucose via the 3-deoxy-3-C-methyl-altroside (42) as outlined in Scheme 13, utilizing an oxidation-reduction sequence to effect double epimerization at C-2 and C-3, and Wittig reactions to lengthen the chain appropriately. 

A synthesis of (-i-)-lycoricidine (45) (glucose numbering) from D-glucose involved addition of an aryl carbanion to an unsaturated... 

Laevoglucosan was used to prepare the hydroxyacid (44) (glucose numbers shown), which was converted into the dimeric macrodiolide, a model for elaiophylin,and 2-deoxy-D-ribose (numbers indicated)... 

The stereochemistry of the a,a-disubstituted amino acid was cleverly controlled using a Pd(0)-catalysed c -hydroxamination involving vinyl epoxide 206, a pnx ess that has been extensively studied by Trost. Ruthenium-mediated oxidation was used to establish the lactone 207 via simultaneous oxidative cleavage of the benzyl ether at C(3) (glucose numbering).
