Where only one methoxy group of a 2Cx drug is cyclised into a dihydrofuran ring, the resulting compound is known as a "hemifly", and when an unsaturated furan ring is used, the compound is known as a "hemi-dragonfly". The larger saturated hexahydrobenzodipyran ring derivatives have been referred to as "butterfly" compounds. The 8-bromo group can also be replaced by other groups to give compounds such as TFMFly
.
A large number of symmetrical and unsymmetrical derivatives can be produced by using different combinations of ring systems. Because the 2- and 5- positions (using phenethylamine numbering scheme, 1,5-positions if numbered as benzodifuran) are not equivalent, all unsymmetrical combinations also have two possible positional isomers, with different potencies at the various 5-HT2 subtypes.

Psychedelic
The term psychedelic is derived from the Greek words ψυχή and δηλοῦν , translating to "soul-manifesting". A psychedelic experience is characterized by the striking perception of aspects of one's mind previously unknown, or by the creative exuberance of the mind liberated from its ostensibly...

Chemistry
2C-B-FLY is 8-bromo-2,3,6,7-benzo-dihydro-difuran-ethylamine. The full name of the chemical is 2-(8-bromo-2,3,6,7-tetrahydrofuro[2,3-f][1]benzofuran-4-yl)ethanamine. It has been subject to little formal study, but its appearance as a designer drugDesigner drug

Analogues and derivatives
In theory, dihydrodifuran analogues of any of the 2Cx / DOx family of drugs could be made, and would be expected to show similar activity to the parent compound. So in the same way that 2C-B-FLY is the dihydrodifuran analogue of 2C-B2C-B
2C-B or 4-bromo-2,5-dimethoxyphenethylamine is a psychedelic drug of the 2C family. It was first synthesized by Alexander Shulgin in 1974. In Shulgin's book PiHKAL, the dosage range is listed as 16–24 mg. 2C-B is sold as a white powder sometimes pressed in tablets or gel caps and is referred...
