Graphical Abstract:
 The current communication represents an extended abstract of the presentation delivered on the joint Moldo-Italian seminar “New frontiers in natural product chemistry”, held in the Institute of Chemistry, Academy of Sciences of Moldova on 31 September. An overview of the synthetic methods oriented to the synthesis of functionalized terpenic perhydrindanes is provided. Different synthetic strategies are considered, including those based on  biomimetic approach. The array of obtained new structures can serve as leads in structure-activity studies as well as useful building blocks towards other perhydrindanes.

Graphical Abstract: 
A selective rearrangement of a epoxy-homodrimanic substrate is described. Using fluorosulfonic acid at low temperature leads by ring contraction to a perhydrindanic structure. On the contrary, using boron trifluoride-diethyl ether at r.t. selectively brings about angular methyl migration.

Graphical Abstract:
The presence of nitrogen in the molecule is usually accompanied either by the appearance of a new activity or the intensification of original activity characteristic for the native terpenoids. This maintains alive the scientific interest in the synthesis of such compounds. The present communication put into discussion the recently elaborated  methods for preparation of the nitrogen-containing terpenic compounds.

Graphical Abstract: 
New effective synthesis of the chiral chinchoninic acids form (-)-α-pinene has been elaborated. It has been shown that, the considerable increase of the yield and purity of chiral acids is achieved applying the method of under phase transfer catalysis.
