Enantioselective total synthesis of macrosphelides A and e

Enantioselective synthesis of 16-membered trilactone macrolides, macrosphelide A and E from (S)-lactic acid is described. Key features of the synthesis include the utility of a hitherto unexplored β-ketophosphonate derived from lactic acid and Yamaguchi lactonization leading to the title compounds.

Benzyl trityl ether and DDQ as new tritylating reagents

We describe herein a new tritylation procedure of alcohols using benzyl trityl ether and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. The reaction involves oxidative abstraction of one of the benzylic protons of benzyl trityl ether, followed by transformation of the generated benzyl trityl ether cation into a complex of benzaldehyde and trityl cation. The present procedure proceeds under mild neutral conditions to afford trityl ethers in generally good yields for primary alcohols, and in acceptable yields for several secondary alcohols.
