Abstract
Abstract: The methyl esters of (&)-pentalenolactone E (5-Me) and F (&Me) have been synthesized by a route based on the intramolecular insertion of an a-acylcarbene into an unactivated CH bond to effect closure of the key fused &lactone ring system. Thus 7, 7- dimethylbicyclo [3.3. 0] octan-3-one (10) was assembled in seven steps from dimethyl 3, 3- dimethylglutarate (13). The requisite (diazoacetoxy) methyl side chain was appended to ...
