资源简介：
The first enantioselective syntheses of cladoacetals
A (1a, overall yield: 16%) and B (1b, overall
yield: 34%) from crotonaldehyde in nine and seven steps, respectively,
have been accomplished. Sharpless asymmetric dihydroxylation, Suzuki
coupling, and acid-catalyzed intramolecular acetalization were the
key steps in the syntheses. The absolute configuration of natural
(+)-cladoacetal A was affirmed to be 1S,3S,4R, whereas that of (−)-cladoacetal
B was affirmed to be 1R,3S,4S.
