Free 4-chlorotryptophan (4-Cl-Trp) was isolated from immature seeds of P. sativum, identified, and its stereochemistry determined to be L-form.Reinvestigation of the N-malonyl-4-Cl-Trp isolated from the same seeds showed that the stereochemistry of the 4-Cl-Trp residue is L-form.

Dichlorotris(triphenylphosphine)ruthenium is highly active as a catalyst for the N-heterocyclisation of 2-aminophenethyl alcohols (2a-d) into indole derivatives in toluene under reflux, and the reactions proceed with spontaneous hydrogen evolution.

A new manganese catalyzed heterocyclization of aminoalcohols has been accomplished. A wide range of heterocycles were synthesized, including 1,2,3,4-tetrahydroquinolines, dihydroquinolinones, and 2,3,4,5-tetrahydro-1H-benzo[b]azepines. The reaction is performed under mild reaction conditions using air and moisture stable manganese catalysts. The desired heterocycles were obtained in good to excellent yields.

Indole derivatives 3 were readily obtained from 2-aminophenethyl alcohols 1 in the presence of 2 mol percent (based on 1) of RuCl2(PPh3)3 under reflux in toluene.Indole (3a) was afforded from 2-aminophenethyl alcohol (1a) quantitatively.Other indoles (3) were also obtained in 73-99percent isolated yields from the corresponding 1, which were easily prepared by condensation between the corresponding 2-nitrotoluenes and aldehydes followed by reduction.During the reaction, a stoichiometric amount of hydrogen was spontaneously evolved into the gas phase.With a heterogeneous and homogeneous binary catalyst system, indoles were afforded in one pot from 2-nitrophenethyl alcohols 2 under a hydrogen atmosphere.
