Participants

Reaction Steps

To a solution of ethyl 2-(4-methyl-N-phenyl-2-vinylnicotinamido)acetate (8) (767 mg, 1.88 mmol) in 1,4-dioxane-H2O (3:1, 20 mL) at RT, osmium tetraoxide (2.5% wt in H2O, 0.5 mL, 0.05 mmol) was added and the resulting mixture was stirred at RT for 30 min. To this mixture, sodium periodate (1.21 g, 5.53 mmol) was added and the resulting mixture was stirred at RT for 30 h. The mixture was filtered through celite and the filtrate was extracted with ethyl acetate (100 mL×2). The combined organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo to afford the product, (S)-3-(1-((9H-purin-6-yl)amino)ethyl)-1-oxo-2-phenyl-1,2-dihydroisoquinoline-8-carbaldehyde (15) (730 mg, 95% yield) as a yellowish solid. ESI-MS m/z: 411.2 [M+H]+.
