The asymmetricsynthesis of the C9N21 fragment of (+)-mycotrienin I is described employing chiral allylsilane bond construction methodology for the installation of the C12C13 absolute stereochemical relationships. In this convergent synthesis the construction of the C9C16 and C17N21 aromatic synthon subunits and their coupling through a lithio dithiane alkylation strategy are detailed.

synthesis. All fourstereogeniccenters were introduced using chiral allylsilane bond construction methodology. In the synthesis of subunit 3b, the C12 and C13 stereocenters were installed using an asymmetric crotylsilylation reaction to α-keto dibenzyl acetal 5. The C11 stereocenter was subsequently installed via a chelate-controlled addition of allyltrimethylsilane to establish the anti-1,3-diol system
