A simple, enantiospecific approach to both enantiomers of 1α,25- dihydroxyvitamin D3 A-ring precursors from R-carvone

A simple and direct approach to both enantiomeric series of A-ring derivatives of 1α,25-dihydroxyvitamin D3 and the corresponding 1α,3α- derivatives, starting from the abundantly available R-carvone, is described. (C) 2000 Elsevier Science Ltd.

Synthesis of new terpene derivatives via ruthenium catalysis: Rearrangement of silylated enynes derived from terpenoids

Enyne rearrangement of silylated modified terpenoids has been used as the key step for the synthesis of new terpenes and terpenoids. The catalytic system generated in situ from [RuCl2(p-cymene]2, 1,3-bis(mesityl)imidazolinium chlorid

Modification of Terpenoid Derivatives with Ruthenium Catalysts Generated in situ

Terpenoids derivatives containing geminal ethynyl and allyloxy groups are easily prepared from the corresponding ketones and aldehydes. The catalytic system generated in situ from [RuCl2(p-cymene)]2, 1,3-bis(mesityl)imidazolinium chloride and cesium carbonate is able to transform these substrates into a new class of terpenoids via cycloisomerisation of the enyne structure.
