A reinvestigation of the marine alkaloid haliclorensin led to a revision of the proposed structure to 7-methyl-1,5-diazacyclotetradecane. The new structure was confirmed by total synthesis of both optical forms. According to chiroptical measurements and GC–MS investigations, natural haliclorensin consists of a 3:1 mixture of the (S)- and (R)-enantiomers.
对海洋生物碱盐蒜素的重新研究导致将拟议结构改制成7-甲基-1,5-二氮杂环十四烷。通过两种光学形式的全合成证实了新结构。根据手足术测量和GC-MS研究,天然水杨素由3:1的(S)-和(R)-对映体混合物组成。
