Abstract
1,5-Polyol structures present challenges in stereocontrol, configurational assignment, and diastereomer separation; these are all compromised by remote stereochemical relationships. A configuration-encoded approach with alcohol configurations previously established within enantiopure building blocks offers a versatile solution to these issues. The iterative construction begins with α-silyloxyaldehydes; here, we introduce an enantioselective and step-economical route from alkynes to α-silyloxyaldehydes via silyl cation-induced ring opening of enol ester epoxides. This development enables an efficient configuration-encoded synthesis of the C22-C41 fragment of the bastimolides.
