The report presents data on our studies on the preparation of the precursor lembehyne A and the complete stereoselective synthesis of natural lembehynes B and C, which have cytotoxic and neuritogenic activity. All methods and approaches to the synthesis of the above-mentioned lembehynes presented in the report are based on the use of the catalytic cross-cyclomagnesiation of 1,2-dienes (Dzhemilev reaction) at the key stage of the synthesis.

Keywords: Lembehynes A-C; 1Z,5Z-dienes; cross-cyclomagnesiation; anticancer and neuritogenic activity
