You should never use the internal commands like '\define@mathgroup'. A
better way to do is described in the manual to the NFSS. With the following
lines you can define a new command '\itmath', which switch to the normal
italic like $\itmath{asc}$.

% itma.sty
% clear for NFSS
\newmathalphabet{\itmath}
\addtoversion{normal}{\itmath}{cmr}{m}{it}
\addtoversion{bold}{\itmath}{cmr}{bx}{it}
\mathversion{normal}
