2C-B

Germenes vary from pale yellow ([—B-r-Bu(Me3Si)2C(B-f-Bu)—] C=Ge[—N-/-Bu(SiMe2)N-/-Bu—]12) to orange-red ((R2CH)-f-Bu-... [Pg.285]

Methylcarborane [l-methyl-l,2-dicarbaclovododecaborane-(12)] may be prepared by hydrolysis of the Grignard reagent formed from the reaction of (bromomethyl)carborane with magnesium in the presence of diethyl ether.2c B h... [Pg.104]

Fig. 1 Solid-state NMR structure analysis relies on the 19F-labelled peptides being uniformly embedded in a macroscopically oriented membrane sample, (a) The angle (0) of the 19F-labelled group (e.g. a CF3-moiety) on the peptide backbone (shown here as a cylinder) relative to the static magnetic field is directly reflected in the NMR parameter measured (e.g. DD, see Fig. 2c). (b) The value of the experimental NMR parameter varies along the peptide sequence with a periodicity that is characteristic for distinct peptide conformations, (c) From such wave plot the alignment of the peptide with respect to the lipid bilayer normal (n) can then be evaluated in terms of its tilt angle (x) and azimuthal rotation (p). Whole-body wobbling can be described by an order parameter, S rtlo. (d) The combined data from several individual 19F-labelled peptide analogues thus yields a 3D structural model of the peptide and how it is oriented in the lipid bilayer...

EXTENSIONS AND COMMENTARY Here is a rather fast-acting psychedelic-like drug, with suggestions of LSD action but with essential differences. It has a lot of things going for it. It is short-lived, a virtue in many people s minds. It may vie with 2C-B as a potential aphrodisiac. It is reasonably easy to synthesize. It is of a pretty high potency. The physical side-effects are minimal. These are the positive points. [Pg.191]

There are two Tweetios known that are related to 2C-B. (See recipe 23 for the origin of this phrase.) The 2-EtO- homologue of 2C-B is 4-bromo-2-ethoxy-... [Pg.29]

I have been told of some studies that have involved a positional rearrangement analogue of 2C-B. This is 2-bromo-4,5-dimethoxyphenethylamine (or... [Pg.29]

Synthesis from 2C-B. To a solution of 7.24 g 2,5-dimethoxy-4-bromophenethylamine (2C-B) and 4.5 g phthalic anhydride in 100 mL anhydrous DMF there was added molecular sieves. After 16 h reflux, the reaction mixture was cooled and the sieves removed by filtration. The addition of a little CH2C12 prompted the deposition of yellow crystals which were recrystallized from EtOH. The resulting l-(2,5-dimethoxy-4-bromophenyl)-2-(phthalimido)ethane weighed 7.57 g and had a mp of 141-142 °C. Anal. (C]gH 6BrN04) C,H,N,Br. [Pg.31]

EXTENSIONS AND COMMENTARY If all the phenethylamines were to be ranked as to their acceptability and their intrinsic richness, 2C-T-7 would be right up there near the top, along with 2C-T-2,2C-B, mescaline and 2C-E. The range is intentionally extended on the lower side to include 10 milligrams, as there have been numerous people who have found 10 or so milligrams to be quite adequate for their tastes. [Pg.61]

If a drug has been initially developed (and initially named) as an amphetamine derivative (three carbon chain) then the two-carbon chain analogue will use the original name (or a symbolic part of it) with the term 2C ahead of it. The two-carbon analogue of DOB (a three-carbon chain compound) will become 2C-B. DOI becomes 2C-I, DON becomes 2C-N, and DOET becomes 2C-E. Each of these is a substituted amphetamine derivative lacking one carbon atom, thus becoming a phenethylamine derivative. Most of these have 2,4,5-substitution patterns. [Pg.102]
