S. Mohialdinkhaffaf et al., 3-HEXANOYL-1-TOSYLINDOLE - A HIGHLY STEREOSPECIFIC PREPARATION OF 3-ALKYL-SUBSTITUTED INDOLES, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 2607-2609
The title molecule, 1-(1-tosyl-3-indolyl)-1-hexanone, C21H23NO3S, is c
onfigured so that the indole moiety eclipses one sulfonyl O atom and t
he toluene ring the other. As expected, the hexanoyl O atom is almost
coplanar with the delocalized indole system.
