Stereoselective total synthesis of (±)-thielocin A1β
Genisson,Tyler,Ball,Young
, p. 11381 - 11387 (2007/10/03)
The stereospicific total synthesis of (±)-thielocin A1β has been achieved from the common intermediate ethyl 5-formyl-2,4-dihydroxy-3,6-dimethyl benzoate (8). The racemic synthesis was achieved based on the key reaction of a 4-methyl-3,4-dihydroxy cyclohe
