Synthesis of C(14',15'), dihydro derivative of the South hexacyclic steroid unit in cephalostatin 1. Part II: Spiroketal synthesis and stereochemical assignment by NMR spectroscopy

Transformation of aldehyde 3 into 2, a C(14',15'), dihydro analog of the 'South' hexacyclic spiroketal of cephalostatin 1 1 is described. The stereochemistry of 2 was elucidated by NMR spectroscopy.
