Bifunctional thiourea catalysts have been found to be excellent promoters of the challenging Michael addition to alkylidenemalonates giving high yields of up to 99%. Substrate structure was important for enantiodiscrimination, with aryl alkylidenemalonate acceptors furnishing products with ee values of up to 73%.

Herein, the route scouting and early process development of a key cyclopentylpyrimidine ketone intermediatetoward the synthesis of Akt inhibitor Ipatasertib are described. Initial supplies of the intermediate were prepared through a method that commenced with the natural product (R)-(+)-pulegone and relied on the early construction of a methyl-substituted cyclopentyl ring system. The first process
