Vertical Forms of Indanes

Since the macros \indanev and \indanevi are included in the style file `lowcycle.sty', they are introduced here. The format of \indanv is: 

   \indanev[BONDLIST]{SUBSLIST}
The locant numbering (1–9) and the bond description (a–j) have a common format as shown in the following diagrams:
\begin{xymspec} \indanev{1==1(lr);2==2(r);3==3(r);4==4(lr);5==5(l);6==6(l);% 7==... ...shiftii,\the\shifti) \\ $\bullet$: (\the\noshift,\the\noshift)}} \end{xymspec}
The handedness for each oriented or double-sided position is shown with a character set in parentheses. Each character in the optional argument BONDLIST indicates a specific double bond as shown in Table [*]. The default setting of BONDLIST produces a fully unsaturated structure, when the option BONDLIST is omitted. If you want to draw a fully saturated structure, you should write down a null option ([]) or [H].

Table: Argument BONDLIST for commands \indolev and others
Character Printed structure Character Printed structure
none or r aromatic six-membered ring H or [] fully saturated form
a 1,2-double bond b 2,3-double bond
c 3,3a-double bond d 4,3a-double bond
e 4,5-double bond f 5,6-double bond
g 6,7-double bond h 7,7a-double bond
i 1,7a-double bond j 3a,4a-double bond
A aromatic circle (six-membered ring)  
B aromatic circle (five-membered ring)  
{n + } plus at the n-nitrogen atom (n = 1 to 9)  

The argument SUBSLIST is used to specify each substituent with a locant number and a bond modifier shown in Table [*], in which n is an arabic numeral between 1 and 7. Substitution on 8 (3a position) or 9 (7a position) can be assigned in the same way.


Example: 

   \indanev{1D==O} \qquad
   \indanev[H]{1D==S;2==COOH}\par
   \indanev[egj]{2D==O;3Sa==H;3Sb==Ph}\qquad
   \indanev[A]{2D==O;3Sa==H;3Sb==Ph}
produce the following structures:
1D==O          [H]1D==S;2==COOH

[egj]2D==O;3Sa==H;3Sb==Ph         [A]2D==O;3Sa==H;3Sb==Ph

The macro \indanevi for drawing indane derivatives of inverse vertical type has the following format (lowcycle.sty). 

   \indanevi[BONDLIST]{SUBSLIST}
The locant numbering and the bond description are common with the vertical counterpart as shown in the following diagrams:
\begin{xymspec} \indanevi{1==1(lr);2==2(r);3==3(r);4==4(lr);5==5(l);6==6(l);% 7=... ...shiftii,\the\shifti) \\ $\bullet$: (\the\noshift,\the\noshift)}} \end{xymspec}
The handedness for each oriented or double-sided position is shown with a character set in parentheses; this is however omitted in the overcrowded position (between 7 and 1). The optional argument BONDLIST specifies bonds to be doubled as shown in Table [*].


Example: 

   \indanevi{1D==O} \qquad
   \indanevi[H]{1D==S;2==COOH}\par
   \indanevi[egj]{2D==O;3Sa==H;3Sb==Ph}\qquad
   \indanevi[A]{2D==O;3Sa==H;3Sb==Ph}
produce the following structures:
1D==O          [H]1D==S;2==COOH

[egj]2D==O;3Sa==H;3Sb==Ph         [A]2D==O;3Sa==H;3Sb==Ph
