The combination of allylic amination, ring-closing metathesis, and a free radical cyclization provides a convenient approach to the dihydrobenzo[b]indoline skeleton, as illustrated in Scheme 10.10. The rhodium-catalyzed aUylic amination of 43 with the lithium anion of 2-iodo-(N-4-methoxybenzenesulfonyl)arrihne furnished the corresponding N-(arylsulfonyl)aniline 44. The diene 44 was then subjected to ring-closing metathesis and subsequently treated with tris(trimethylsilyl)silane and triethylborane to afford the dihydrobenzojhjindole derivative 46a in 85% yield [14, 43]. 

Other BAs, such as putrescine (Put), cadaverine (Cad), tryptamine (Try), /3-phenylethyl-amine (Phe), spermine (Spm), and spermidine (Spd), have been described as potentiators that enhance the toxicity of His (21,22) likewise, Tyr and Phe are thought to precipitate migraine attacks in susceptible subjects (23). 

Metal template syntheses of complexes incorporating the p-amino imine fragment have been introduced by Curtis as a result of his discovery that tris(l,2-diaminoethane)nickel(II) perchlorate reacted slowly with acetone to yield the macrocyclic complexes (40) and (41) (equation 8).81-83 In this macrocyclic structure the bridging group is diacetone amine imine, arising from the aldol condensation of two acetone molecules. This reaction is widely general, in the same way that the aldol reaction is, and can be applied to many types of amine complexes. The subject has been reviewed in detail with respect to macrocyclic complexes by Curtis.84...

Figure 180 The range (Ze) of electrons (right ordinate) and the recombination probability [P ] for electrons (left ordinate). A comparison between the theoretical predictions according to Eqs. (153) and (328) (lines) and experiment (data points) shows good agreement for the electron mobility jie = 3.3 x 10-8 cm2/V s (a). Schematic cross-section of the EL device and monitoring of emission from two different emitters (PSu + TSA)—a blend of polysulfone (PSu) and tris(stilbene)amine(TSA), and PPV-poly(phenylenevinylene). Their thicknesses (dly d2) are subject to variation, d0 is the quenching zone of excitations by the Ca cathode (b). Adapted from Ref. 344.

Much of the extensive work that has been done on 5-hydroxytrypt-amine (HT serotonin) since its isolation and identification twenty years ago has been directed to uncovering its possible function in neural activity. As no short review can include references to all the numerous contributions, the authors have tried to select those references that are recent and include a significant bibliography. No attempt has been made to designate priorities for the observations. Two books and a symposium scheduled for publication in 1968 provide full references and detailed discussions of all aspects of the subject. 

The alterations produced by THC and other cannabinoids in biogenic amine levels as well as on uptake, release and synthesis of neurotransmitters and effects on enzymes have been the subject of numerous investigations (for reviews see [8,52,55,114,115]). It is beyond the scope of the present summary to try to analyse and put into a proper perspective the wealth of data published so far. It is our subjective view that the mode of action of cannabi-mimetic compounds is somehow directly associated with prostaglandin metabolism (see, in particular, the series of papers by Burstein [115,116]), and/or reduction of hippocampal acetylcholine turnover observed in rats [117,118]. The latter effect is enantiospecific and follows the known SAR of the cannabinoids. This in vivo selectivity of action suggests that the THC may activate specific transmitter receptors which indirectly modulate the activity of the cholinergic neurons in the septalhippocampal pathway.
