Abstract:

Hydroboration of 1-allyl-1,2,3,4-tetrahydroquinoline (I) with triethylamine-borane in the molar ratio 1 : 1 afforded a product from which 6,7-benzo-5-aza-1-boraspiro[4,5]decane (II) was isolated. Ethanolysis of II gave diethyl 3-(1,2,3,4-tetrahydro-1-quinolyl)propylboronate (III). Acid hydrolysis of the crude hydroboration product and subsequent oxidation with alkaline hydrogen peroxide led to a mixture of 3-(1,2,3,4-tetrahydro-1-quinolyl)-1-propanol (IV), 1,2,3,4-tetrahydroquinoline (V) and 1-propyl-1,2,3,4-tetrahydroquinoline (VI).
