Abstract
The platform C14-C40, which can be used to prepare bistramide C and 39-oxobistramide K, was synthesized in 19 steps with an overall yield of 6.2%. Furthermore, the chemoselective reduction of the ketone at C-39 was performed giving an easy access to bistramides A, B, D, K, and L. Finally, the versatility of the synthesis of the C14-C40 fragment can allow the preparation of a large variety of stereoisomers to produce bistramide analogues.

Abstract
Synthesis and preliminary biological evaluation of a 35-member library of bistramide A stereoisomers are reported. All eight stereoisomers of the C1-C13 tetrahydropyran fragment of the molecule were prepared utilizing crotylsilane reagents 9 and 10 in our [4+2]-annulation methodology. In addition, the four isomers of the C14-C18 gamma-amino acid unit were accessed via a Lewis acid mediated crotylation reaction with use of both enantiomers of organosilane 11. The spiroketal subunit of bistramide A was modified at the C39-alcohol to give another point of stereochemical diversification. The fragments were coupled by using a standard peptide coupling protocol to provide 35 stereoisomers of the natural product. These stereochemical analogues were screened for their effects on cellular actin and cytotoxicity against cancer cell lines (UO-31 renal and SF-295 CNS). The results of these assays identified one analogue, 1.21, with enhanced potency relative to the natural product, bistramide A.

Abstract
An asymmetric synthesis of the marine metabolite bistramide A is reported. The synthesis relies on the utility of three different organosilane reagents to construct all principle fragments and 8 of the 11 stereogenic centers of the natural product. [structure: see text].

Abstract
[reaction: see text]. New chiral crotylsilanes that bear a (Z)-olefin geometry were synthesized in high enantiopurity. The reagents participate in [4 + 2]-annulations with aldehydes to give stereochemically complementary pyrans (relative to (E)-crotylsilanes) bearing 2,6-cis-5,6-cis and 2,6-trans-5,6-cis relationships of peripheral functionalities. A stereoselective synthesis of the C1-C13 fragment of bistramide A is also described highlighting this annulation strategy.

Abstract
The enantioselective synthesis of bistramide A has been achieved with a longest linear sequence of 18 steps. The synthetic strategy involves the use of a distereoselective glycolate alkylation, an aldol addition of a chlorotitanium enolate of N-acylthiazolidinthione, and a Sharpless asymmetric epoxidation to synthesize the three key fragments.
