Lappaconitine and N deacetyllappaconitine derivatives containing bromine and iodine atoms in the aromatic moiety were synthesized. The Heck cross coupling of these halides with ethyl acrylate or 2 methyl 5 vinylpyridine afforded new olefinated lappaconitine derivatives.

3 Arylprop 2 ynylamines containing the key fragment of known alkaloids of the Altai flora were synthesized by the Sonogashira and Mannich reactions.

A method for N-deeH~ylalion ofditerpene alkaloids of the aconicane type by the Cope reaction was developed using conversions of lappacomthm and elatine as examples. The previously unknown hi:tones of N-deethyla~ed tappaconifine, daline, and elatidine were prepared

This paper reports on a two-week nethnographic (online) observation of four online gift-exchange communities – virtual platforms, where participants conduct barter exchange of different daily objects such as books, children's products, furniture, home ware and others. These communities as case of informal economy initially do not have formal attributed rules. It is essential to find out (1) which rules and mechanisms exist in this type of economy; (2) what motivates people who are not acquainted with another to exchange gifts; and (3) understand the way this community exists. The conclusion is drawn that social capital is the basic engine of investigated communities. The social capital accumulated by users increases the community commitment and cohesion by interpreting gifts as a set of resources to distribute fairly. The giving, the receiving and the exchanging are forms of communication that cause further communication and interworking outside of gift-giving situations. These gift-exchange communities are mainly based on the communication and consumption solidarity among individuals.
