Yf. Zhao et al., DOUBLE MICHAEL REACTION OF CARVONE AND IT S UTILIZATION IN CHIRAL SYNTHESIS OF NATURAL-PRODUCTS, Huaxue xuebao, 52(8), 1994, pp. 823-830
The double Michael reaction of carvene and methyl methacrylate was des
cribed in detail. Its product, an optically active bicyclo [2.2.2]octa
ne derivative, is a useful intermediate for the chiral synthesis of na
tural products. In this respect an elemene derivative and an intermedi
ate for the synthesis of (+)-curdione were synthesized.
