(S)-α-Trimethylammonio aldehydes have been synthesised over several steps from corresponding amino acids. The dichroic carbonyl absorption can be rationalised in terms of the Octant Rule with the assumption of a preferred conformation. The chiroptical properties of intermediate α-phthalimido aldehydes have also been investigated.
(S)-α-三甲基
氨醛已经从相应的
氨基酸经过数步合成。假设优选构象,则可以根据Octant法则合理化二色性羰基吸收。还已经研究了中间α-邻苯二甲
酰亚胺基醛的手性。
