YieldReaction ConditionsOperation in experiment
Combinatorial reaction / High throughput screening (HTS); Libraries were prepared in a single compound per well format. Stock solutions of all aldehydes (0.5 M) and aryloxyamines (0.4 M) were prepared in DMSO. A Gilson 215 Liquid Handler equipped with a 1 mL syringe, 1.1 mL tubing, and a 13 mm I.D. probe was used to distribute all solutions into a 96 well (2 mL volume) polypropylene plate at a rate of 0.3 mL/min. To make 0.5 mL of a 0.1 M solution of each oxime ether, 100 muL (0.05 mmol, 1 eq.) of aldehyde, 156 muL (0.63 mmol, 1.25 eq.) of aryloxyamine, and 244 muL of 0.164 M acetic acid, were distributed to each well of the plate. The plate was covered and agitated for 24 h at room temperature using a dual action shaker. The reactions were diluted to 720 muM in DMSO and analyzed by LC-MS to determine yield, purity, and identity. Compounds were stored frozen at -20 C. after synthesis. Reaction yield was determined using the integrated value of aldehyde that remained in the reaction mixture. Calibration curves of all aldehydes were made and the yield of each oxime ether was calculated assuming all the aldehyde that reacted quantitatively formed oxime ether; i.e. if 5% of aldehyde remained in the reaction mixture the yield of oxime ether would be 95%. Yields ranged from 98-100% and >95% purity in all wells.
