Prior to those there were LSZ (lysergic acid dimethylazetidide) and AL-LAD doing the rounds in the UK. Very briefly PARGY-LAD too.

1P-LSD was something of a breakthrough IIRC (never tried it but I was still following the scene at that point) because unlike the others it is a pro-drug for LSD, being quickly metabolised to the parent compound, rather than a different but closely related compound as the others were.

Never heard of the rest of those though! I stopped paying attention sometime around then.
