日期:1999.7.1
Aldolase antibody 38C2 catalyzes the enantioselective aldol cyclodehydration of 4-substituted-2,6-heptanediones (3) to give enantiomerically enriched 5-substituted-3-methyl-2-cyclohexen-1-ones (4). Yields, enantioselectivities, and product purities are markedly increased compared to the L-proline-catalyzed reactions.

β-Enones undergo an efficient Hosomi-Sakurai reaction with allyltrimethylsilane, in which a catalytic amount of indium is used in the presence of trimethylsilylchloride as an activator under mild conditions to produce the conjugateaddition products in good yields.
