Dispiroketals in Synthesis (Part 19): Dispiroketals as Enantioselective and Regioselective Protective Agents for Symmetric Cyclic and Acyclic Polyols.

The enantioselective preparation of both enantiomers of a C2-symmetric diphenyl-bidihydropyran 3 and 4 is described.The application of enantiopure bi-dihydropyrans 1-4 towards the simultaneous enantioselective differentiation and regioselective protection of a range of cyclic and acyclic symmetrical polyols (23, 37, 43, 45, 54, 61 and 66) is investigated.Several deprotections utilising trifluoroacetic acid (TFA) and a transketalisation with acidic glycerol are presented.

Dispiroketals in Synthesis (Part 11): Concomitant Enantioselective and Regioselective Protection of 2,5-Dibenzoyl-myo-inositol.

2,5-Dibenzoyl-myo-inositol, a symmetrical polyol, may be simultaneously enantioselectively and regioselectively protected using the chiral dienes (1), (2) and (3).Deprotection, to afford D or L-1,6-tetra-O-benzyl-myo-inositol (8) and (12) respectively, wa
