A modular and highly stereoselective synthesis of the title compound was developed. Key steps in the assembly of the carbon framework of ripostatinB (1; see scheme) were a stereoselective Paterson aldol reaction and a high‐yielding ring‐closing metathesis mediated by Grubbs first generation catalyst. The C15 hydroxy group was established through Tishchenko–Evans reduction in excellent yield and selectivity
