Abstract:
New isopimaric acid derivatives containing amines and methyl esters of α-, β-, and ω-amino acids were prepared. Conditions were found for cyclic isomerisation of isopimaric acid propargylamide into 2-(dodecahydrophenanthren-1-yl)-5-methyloxazole or 2-(dodecahydrophenanthren-1-yl)-5-methylene-4,5- dihydrooxazole. The latter was selectively modified by adding the methyl ester of (2-methylamino)butanoic acid at the oxazole C-5 position.
