摘要

(R)-and (S)-[2-2H] glycine of high chiral purity were synthesized in large quantities in≈ 40% overall yield from readily available starting materials via a totally chemical procedure. Reduction of either [1-2H]-furfural or [1-2H]-4-methoxybenzaldehyde with either (+) or (-)-B- isopinocampheyl-9-borabicyclo [3.3. 1] nonane gave chiral arylmethyl alcohols which were converted into their respective phthaloyl amino derivatives of the opposite configuration at ...
