Synthesis of optically active myo-inositol 1,3,4-trisphosphate has been accomplished. Efficiency of a chiral HPLC column for optical resolution of myo-inositols is shown.
A new total synthesis of (±) norpatchoulenol is described with a ScN′ type reaction as the key step.

In continuation of studyingstructure/activity relationships of odorous compounds, the influence of the bridgehead-bonded Me group of (+)-norpatchoulenol (1) and (−)-patchoulol (2) and the olfactory properties of the corresponding unsaturated and saturated derivatives (±)−3, (±)−4 and (±)−5, (±)−6, respectively, are studied. The key odour descriptors-wood, earth, and camphor-are used for classification

A process for the preparation of tricyclic compounds is described in which novel intermediate compounds of the general formula
in which R represents hydrogen or alkyl having up to 5 carbons, the dotted line represents an optional carbon-carbon bond and OR' represents a leaving group is cyclised using an alkali metal in an organic solvent, followed, if desired, by hydrogenation to give compounds of the formulae
Compounds of formula I and VI are useful as odoriferous agents having patchouli type odours and, with the exception of norpatchoulenol, are new.
描述了一种制备三环化合物的工艺,其中通式如下的新型中间化合物
其中 R 代表氢或最多 5 个碳原子的烷基,虚线代表任选的碳-碳键,OR'代表离去基团 在有机溶剂中使用碱金属进行环化,然后根据需要进行氢化,得到式 I 和式 VI 的化合物。
式 I 和 VI 的化合物可用作具有广藿香类气味的增臭剂,除了去藿香正气水醇以外,它们都是新化合物。
