Stereoselective total synthesis of polyketide lactone, (3R,4S,5S,9S)-3,5,9-trihydroxy-4-methylundecanoic acid δ-lactone

Sabitha, Gowravaram,Gopal, Peddabuddi,Yadav, Jhillu S.

, p. 1493 - 1499 (2009)

The total synthesis of lactone 1 has been described. The convergent asymmetric synthesis relies on the use of an Evans' syn-aldol, chain extension with lithio tert-butyl acetate, and the stereoselective reduction of a ketone as the key reactions.
