Abstract Several stereoselective routes to the synthesis of (1S,3R)-t-butyldimethyl-(1-methyl-3-oxiranyl-propoxy)-silane ( 13a ) were explored, and the use of Jacobsen's hydrolytic kinetic resolution to separate a mixture of diastereomeric epoxides was a key step in the shortest of these. As part of an approach to the total synthesis of amphidinolide T2 ( 2 ), this epoxide, corresponding to C17–C22
