Abstract
An iterative strategy to the 1,3-polyol motif is described. The
use of the catalytic asymmetric Overman esterification for the construction
of all stereogenic centers is broadly examined as are the sequences
to extend the developing polyol chain. The iterative strategies
are applied to the total syntheses of rugulactone and polyrhacitides
A and B.

34 It should be mentioned that the use
of triethylsilyl protecting groups does not show these deprotection
issues, see: ref. 24.
35 The syn -configuration
of 10a was shown by conversion into polyrhacitide
A (ref. 43) and comparison of the analytical data. The syn -configuration of 10b was
shown by conversion into (3R ,5R )-5-(tert -butyldimethylsiloxy)-3-(triethylsil-oxy)hexanal
and comparison of the analytical data with previously reported data: Nicolaou KC.

38 It has to be noted that the isolation
of aldehyde 16 is somewhat troublesome,
and, therefore, it is recommended to use it without further purification
(see ref. 36d). Nevertheless, 16 can be
isolated and stored at -20 ˚C over weeks without
decomposition. See the experimental section and the Supporting Information
for analytical data.
