Abstract
Three trace alkaloids from Colorado blue spruce, Picea pungens, were identi fied by synthesis and GCMS comparisons as 4 alpha-hydroxy-cis-2-methyl-6-(2 -oxopropyl)piperidine (1),4 alpha-hydroxy-cis-2-methyl-6-propylpiperidine ( 11), and 1-methylgranatanone (15) (N-methyl-9-aza-1-methylbicyclo[3.3.1]non ane or N-methyleuphococcinine). Alkaloids 1 and 11 are the first among nume rous known pine and spruce piperidines to contain a ring-oxygenated substit uent.
