Hi, I am moving my vanity sink from the left side, where the plumbing is coming out of the wall, to the center. The problem is connecting the sink tailpiece to the drain. That is a 1 1/2" connection coming from the wall. Are there elbows or adapters to do this? I tried this extension but it doesn't seem to work.

What you want to do is a real bad idea. Don't do it. Don't use this corrugated bad idea.
We move sinks all the time, and every time we have to custom fit the drain.
If you have knowledge in doing just that, do the custom fitting, otherwise, find a plumber.

The trap will only protect the room from sewer smells from things PAST it...that corregated pipe will accumulate lots of soap scum, hair, etc., and begin to smell really nasty fairly soon. Use smooth walled drain tubing. You can add a couple of elbows in there, I think, to get things to align. It's never great to have that tubing leading to the drain very long, but it can work. Without opening the wall, you'll never know if there's an easy way to do it in the wall.

Good example of bad things that are sold to unsuspecting DIY. Just because stores stock them doesn't make them proper.

I agree; not a big fan of the gooseneck thingy. I will sometimes use a slip-joint 45 to get me over to a relocated lavatory drain.

That will work as long as the horizontal section is sloped towards the trap. IF it is level or slopes back, you'll have issues. Waste doesn't flow uphill very well!
I'm assuming that there's a vertical pipe from the bottom of the sink. The height of the sink outlet needs to be above where the outlet of the p-trap goes into the wall.

It looks like the horizontal run would stay full of waste water. Is there a reason you have the trap reversed?

No. You need to remove the trap adapter in the wall and use a 45 there to bring the trap arm towards the trap. The trap needs to stay on the bottom of the sink tailpiece.

From the sink down, at the bottom of the drain set, that's where the P trap should be, then an arm to the drain in the wall.
Angles and length of drain lines can be decided on the spot - this is what customizing your drain means..
Your latest picture proposal is not good.

Yes, that's better but the horizontal still needs to slope to the drain at least 1/4" per foot otherwise, stuff will tend to accumulate there. A 90-degree isn't ideal...a 45 would be better. The trap can be at any 'wrap', so in your situation, the inlet to the trap could be to the left with the outlet to the right

Just cut a short piece of pipe from one of your parts and install it in the trap adapter at the wall. Then attach the slip joint 45 to that and go from there. Hopefully, that assembly will get you over to the vicinity of the lavatory drain, and you can properly install the trap directly beneath the lavatory.

If he was a plumber, he'd be out there doing it, making four times the money. Looks like another slip joint 45 might get you connected. Gluing up a lavatory drain can make things difficult for someone later on if you get a clog.

It looks like you can make that work with a tailpiece extension. You don't want to exceed 1/4" per foot in pitch between the trap and the vent in the wall.
