An efficient stereoselective synthesis of the C1-C10 fragment of narbonolide is reported. The stereocentres at C2, 3, 4, 5, 8 and 9 in fragment 5 can be generated via an iterative asymmetric acyl-thiazolidinethione aldol reaction, whereas the stereocentre at C6 is installed by means of Myers alkylation.

An efficient stereoselective synthesis of the C1-C10 and C11-O14 fragments of narbonolide, have been accomplished by using a thiazolidinonethione as chiral auxiliary. The stereocenters at C2, C3, C4, C5, C8, and C9 in C1-C10 fragment and C12 and C13 in C11-C14 fragment were generated via asymmetric acyl-thiazolidinethione aldol reactions whereas the stereocenter at C6 was installed by means of Myers
