The Grieco intermediate 2, for the synthesis of the Prelog-Djerassi lactone, was obtained from trans-pulegenic acid 3 in 6 steps in 43 % overall yield; recycling unwanted diastereoisomer 8(S), increased the yield to 56 %.

The (+)-Prelog-Djerassi lactone methyl ester 1 was obtained from trans-pulegenic acid 2 in seven steps in 22 % overall yield; three more steps from an unwanted diastereoisomer gave additionnal 5%.
