YieldReaction ConditionsOperation in experiment
52%; > 95% General procedure: To 6.6 g (13 mmol) of 1 in 30 ml of MeCN were added 5.4 g (39 mmol) of K2CO3 and 26 mmol of the nucleophile 2a (8.4 g), 2b (9.0 g), 2c (7.2 g), 2d (5.18 g) 2e (6.01 g), 2f (5.5 g), 2g (5.67 g), 2h (5.67 g), 2i (4.58 g), 2j (6.63 g), 2k (5.05 g), 2l (3.28 g), 2m (8.54 g), 2n (5.31 g). The reaction mixture was stirred at room temperature or at 50 C (in case of 2a, 2g, 2h, 2m, and 2n) under an argon atmosphere. The course of the reaction was monitored by TCL (SiO2, CH3COCH3/CHCl3, 1:3) by following the disappearance of the initial complexes 1. Upon completion of the reaction, the mixture was filtered and extracted by CHCl3 (3 × 50 ml). A small part of the mixture (0.5 g) was separated by column chromatography (20 × 30 cm, SiO2, CH3Cl/CH3COCH3 (5:1)) and the structure and absolute configuration of the pure major diastereomer of complexes 3a-n were established by spectroscopic methods. 4.3. Isolation of the target amino acids 4a-n. Decomposition of the diastereomeric complexes 3a-k and isolation of the target beta-substituted alpha-amino acids 4a-k were carried out according to the literature.(d) and (e)
