Abstract
A synthesis of 1233A [(2__E__,4__E__,7__R__,2′R,3′R)‐11‐[3′‐(hydroxymethyl)‐4′‐oxo‐2′‐oxetanyl]‐3,5,7‐trimethyl‐2,4‐undecadienoic acid (1a)] was achieved by employing (R)‐2‐hydroxymethyl‐3‐butenyl acetate (2a) and (R)‐citronellic acid (3) as chiral building blocks. The former was prepared by lipase‐mediated asymmetric hydrolysis of the corresponding diacetate.
