A ketal-tethered RCM strategy toward the synthesis of spiroketal related natural products

An unconventional approach to construct spiroketals and spiroaminals via ring-closing metathesis [RCM] of cyclic ketals and aminals, respectively, is described here. This method possesses a good generality with no loss of stereochemical integrity at the s

Synthesis of the C11-C23 fragment of spirastrellolide A. A ketal-tethered RCM approach to the construction of spiroketals

(Chemical Equation Presented) The synthesis of the C11-C23 fragment in spirastrellolide A is described here featuring a ketal-tethered RCM as an alternative approach to the construction of spiroketals.
