Correct. 5-propyl-resorcinol, aka divarinol would be condensed with citral to yield THCV. 3-hepten-2-one is what you’d use for the total synthesis of divarinol instead of 3-nonen-2-one for olivetol.
I synthesized divarinol and condensed it with geraniol to produce CBGV. I then carboxylated it to CBGVA and fed it to THCA synthase to produce d9 THCVA, or to CBDA synthase to produce CBDVA.
CBDV can be isomerized to d8 or d9 THCV using the same methods as CBD to THC.
