Two regiospecific consecutive alkylations of carvone at C6 followed by acid-catalysed cyclisation afford bicyclic ketones which are potential intermediates for the synthesis of several classes of terpenes.Depending on the sequence of alkylation trans fused ketone 7 or mixture of 7 and cis fused 13 may be prepared in only three steps, thus constituting a new type of annulation of carvone.
A NEW CHIRAL ROUTE TOWARD TERPENOIDS. ANNULATION OF CARVONE TO TRANS- AND CIS-FUSED BICYCLIC SYNTHONS

, p. 5853 - 5866 (2007/10/02)
Starting from carvone, 1 two consecutive alkylations at C-6 followed by an acid-catalyzed cyclization give new bicyclic ketones which are potentially useful chirons for synthesis of terpenes such as drimanes, labdanes and triterpenes.The stereoselectivity
