The Spell Vampiric Touch states:
Your touch deals 1d6 points of damage per two caster levels (maximum
10d6). You gain temporary hit points equal to the damage you deal. You
can't gain more than the subject's current hit points + the subject's
Constitution score
So could you cast the spell on yourself, gain up to your own Hits+Constitution in temporary hit points and then subsequently get a cure to get yourself extra hit points?
Note: For interests sake (and so the caster doesn't potentially kill themselves) you can cast spells at a lower level than normal as long as it's high enough to cast said spell.

Yes, you can target yourself.
However, note that multiple castings do not stack. It’s a same-source issue; you can’t keep casting the spell to get more. So you get 1d6/2 levels worth of HP (average 1.75/level, which won’t approach the cap unless you are badly hurt and have very low Constitution), which is poor compared to false life’s 1d10+level (average 5.5+level) at least until CL 8. Note that even after that, false life is lower level, has a far longer duration, and doesn’t hurt yourself.
Though I guess you could do both, since they stack with each other, so that’s obviously going to be higher. Still better if you’ve got a target who you don’t care about healing, though.
