There are six ring residues attached to the carbon atoms of the entire conjugated
system, one double bond extending conjugation, two exocyclic double bonds
and one double bond exocyclic to two rings simultaneously. Thus, ATM,x of this ...

Modern Physical Organic Chemistry
Using Isotopic Scrambling to Distinguish Exocyclic vs. Endocyclic Cleavage
Pathways for a Pyranoside The hydrolysis of pyranosides is postulated to largely
proceed via exocyclic cleavage to give a cyclic oxocarbe- nium ion (Path A).

Nucleic Acids in Chemistry and Biology
To achieve this selectively it is necessary to protect the nucleobase exocyclic
amino groups and the 5-hydroxyl group. 4.1.2.1 Nucleobases. Permanent
protecting groups for the exocyclic amino groups of adenine, cyto- sine and
guanine have ...

Spectroscopy of Organic Compounds
On the related monocyclic system p-phellandrene two additional factors need
consideration, i.e., now there are two ring residues (carbon substituents) on the
diene system and one of the double bond has become exocyclic to the ring.

Ribozymes and RNA Catalysis
However, these results still cannot distinguish whether the neutral or protonated
form of C75 contributes to ribozyme function. The exocyclic N4 amino group of
C75 has been proposed to help position the catalytic base and shift the pKa of
C75 ...

On the other hand, loss of a proton from the methyl group yields
methylenecyclohexane, in which the double bond is outside the ring (exocyclic).
As stated in Chapter 2, the more highly substituted alkene is generally more
stable.

Additions to and Substitutions at C-C Pi-Bonds
The complexes derived from methylene- cyclopentane and
methylenecycloheptane both exhibit exclusive exocyclic addition by the anion of
methyl(methylsulfonyl) acetate with triphenylphosphine ligands on the Pd (
equation 225). In contrast ...

Oxidative Damage to Nucleic Acids
This is ascribed to the predominant formation of the exocyclic species with
cytidine. With the purines, where multiple species can potentially be formed,
analyses of the complex decay curves obtained suggest that both endo- and exo-
cyclic ...

Comparing the chemical structures of BF8, BF9 and BF10, it was found that BF8
contains a exocyclic vinyl bromide group (=CH-Br), while BF9 and BF10 contain
a exocyclic vinylidene bromide group (=C-Br2). This finding suggests that ...
