Tryptamine hydrochloride

Tryptamine hydrochloride [343-94-2] M 196.7, m 252-253 . Crystd from EtOH/water. 

Kreuger and Carew (141) examined the effects of a number of alkaloid precursors on alkaloid production in suspension cultures and found that at 100 mg/liter tryptamine hydrochloride enhanced alkaloid production. The alkaloids produced, however, were A-acetyltryptamine and N,N-dimethyltryptamine, rather than the monoterpenoid indole alkaloids. Added geraniol and mevalonic acid had no effect on alkaloid production. 

In a 1-1. Erlenmeyer flask, 25 g. (0.13 mole) of tryptamine hydrochloride (Note 1) is dissolved with stirring in 400 ml. of water by warming on a steam bath to approximately 45°. After...

Pictet-Spengler reaction of 2,5-anhydro-D-mannose (55) and tryptamine hydrochloride (56) at ambient temperature affected the tetrahydropyri-dine ring formation of the (li ) and (15)-l-(a-D-arabinofuranosyl)-l,2,3,4-tetrahydro-/3-carboline 57 [830C2721, 83JCS(CC)601] (Scheme 18). 

Nitrovinyl)indole (15 g) is extracted during 8 h from a Soxhlet thimble into a flask containing LiAlH4 (15 g) in anhydrous ether (300 ml). The mixture is then treated with water (80 ml), slowly and with cooling, and filtered. The ether solution is separated, dried over sodium sulfate, and saturated with hydrogen chloride. Tryptamine hydrochloride (12.7 g) is thus obtained, melting at 249-250° (decomp.) after recrystallization from methanol-ethyl acetate. 

A concentration of 25 millimoles of tryptamine hydrochloride is added to 10 grams mushroom substrate (spawn media). The substrate is composed of either rye grain spawn or hce spawn. The following spawns can be used for the culture of many species of mushrooms.

A soln. of 2-(2-nitrophenylthio)tryptamine in 15%-acetic acid heated 10 hrs. at 110° in a sealed tube, and the product isolated as the hydrochloride 2-hydroxy-tryptamine hydrochloride. Y 74%. - This reaction is assisted by the free amino group. F. e. s. F.M. Veronese et al., Z. Naturf. 23b, 1319 (1968). 

Most recently we have studied the charge-transfer interactions between polyelectrolytes and several substrates [50]. The complex formation of tryptamine hydrochloride with polyvinylpyridine quatemized with butyl chloride [C4PVP] is due to charge-transfer interactions, which overwhelm the electrostatic repulsive forces between the two cationic substrates. Addition of potassium chloride and calcium chloride (0.5 eq. r increased the complex formation constant (A) (from 13) to 37 and 57 (1 eq. at [C4PVP] =...
