=Conclusion= =Log= 12:30 Made-up 1.5M solution of phenanthrene-9-carboxaldehyde by dissolving the solid aldehyde (2.8g, 13.57mmol, 2.30mL) in THF (6.75mL) 13:00 Made-up a 3M solution of Boc-glycine by dissolving the solid acid (2.5g, 14.27mmol, 2.157mL) in THF (2.5999mL) 13:20 Made-up a 3M solution of phenylacetic acid by dissolving the solid acid (0.8g, 5.875mmol, 0.6872mL) in THF (1.2713mL) 13:45 Labeled 11 one dram vials **247-1 to 247-11** 14:00 Pipetted out phenanthrene-9-carboxaldehyde solution (666.7uL, 1.5M in THF) in to the vial labeled 247-1 to 247-11 14:15 Pipetted out corresponding amine in to the vials (see spreadsheet for the name and volume added), vortexed the vials for 15s each. 14:30 Pipetted out boc glycine solution (333.4uL, 3M in THF) in vials 247-1 to 247-8, vortexed the vials for 15s each. 14:35 Pipetted out phenylacetic acid solution (333.4uL, 3M in THF) in vials 247-9 to 247-11, vortexed the vials for 15s each. 14:55 Pipetted out corresponding isocyanide in to the vials (see spreadsheet for the name and volume added), vortexed the vials for 15s each. 15:03 Obtained a picture of the reaction mixtures in the vials- **UCExp247-IMG-i** 16:40 Vial 247-3 had formed a solid ppt in it. Obtained a pic of the vials, **UCExp247-IMG-ii** 16:55 Vortexed all the vials for 15s each. 17:00 Pipetted out THF (500uL) in to vial 247-3 and vortexed and mixed the contents thoroughly. 17:05 Centrfuged vial 247-4 and separated the supernatant from the residue--collected the supernatnat separately 17:10 Repeated the THF (500uL) was of 247-3 another two times and collected the supernatant each time in to the previously collected supernatant. The combined supernatant is now labeled **247-3B** 17:15 The residue obtained was set under a high vac for the solvent to evaporate. 10:30 Removed 247-3 from the high vac and obtained **247-3A** (xx mg, yield xx%) 11:55 Off the remaining ten reactions, 8 have formed precipitates, obtained a picture of the vials- **UCExp247-IMG-iii** 12:10 To the vials which had ppts (247-1, 274-2, 274-4, 247-5, 247-6, 247-7, 247-8 and 247-10) THF (500uL) was added. The vials were then vortexed to homogenize the solution. The vials were then centrifuged for about 2-3min. The supernatant was separated from the reside and the clear supernatant were collected and labeled accordingly as **247-1B** to **247-8B** and **247-9B.** 15:45 THF wash repeated another two times (total of 3) and the obtained residues from the vials were left in the high vac to dry. Sample vials 246-6 and 247-7 yielded a very small amount of the solid after the wash. 16:00 Vials 247-9 and 247-11 did not form ppt even after 24h..the reactions in the vials is therefore aborted. 12:20 Removed the vials from the desiccator and obtained dry powders...all vials contained white powder except vial 247-6 and 247-7 which were off-white. The products obtained after drying are labeled **247-1A,** **247-2A,** **247-3A,** **247-4A,** **247-5A,** **247-6A,** **247-7A,** **247-8A** and **247-10A.** 13:00 The mother-liquors (**247-#B** series) from THF wash had evaporated off completely (they were left open in a fume hood). The residues were washed with methanol (3x 1mL) and the solid obtained after the wash was left to dry in a desiccator on a high vac. 18:00 Submitted a small portion of each sample from series 247-#A for mass analysis.
