11277773-4	2001	Efforts to establish the C10 and C13 spiroketal centers via an oxonium-initiated bis-spiroketalization under both kinetic and thermodynamic conditions have yielded the (10R,13S)-trioxadispiroketal 19 as the major product, which is diastereomeric with the (10R,13R) relative configuration assigned to the azaspiracids.	hydronium ion	63-70	homeobox C10	Homo sapiens	25-28
