    • The configurations of 10 and 11 could not be assigned a priori; they were determined by correlation to the corresponding N,O,O,O-tetra-acetyl phytosphingosines 12 and 13. The (4S,5S,1′S)-configuration of the major diastereoisomeric product 10 is consistent with Si face attack of the Grignard on aldehyde 9 via a chelated Cram model; see:
