• Syntheses and Theoretical Studies of Exocyclic .gamma.-Oxoalkenyltrimethylsilanes. An Approach to the Stereodefined Exocyclic Tetrasubstituted Alkenes

  The Z-selectivity in the dehydration of alpha-hydroxy-gamma-oxoalkyltrimethylsilanes under acidic conditions was studied from experimental and theoretical points of view. Experimental results showed that (Z)-gamma-oxoalkenyltrimethylsilanes were thermodynamic products under these conditions. The dehydration studies of the compound involving the tert-butyl group instead of the TMS group pointed out that not only steric but also electronic effects of Si could contribute to the distribution of the products as well as their stereochemistries. Theoretical studies using ab initio calculation at the 6-31G* level indicated that the (Z)-isomer was thermodynamically more stable than the corresponding (E)-isomer. Detail examinations of the optimized structures showed that the configuration of Si in the (Z)-isomer was slightly distorted from tetrahedral. Interpretation of the geometrical change of Si to rationalization of the thermodynamic preference was discussed fi om the viewpoint of possible coordination of the carbonyl oxygen to Si. Those (Z)-gamma-oxoalkenyltrimethylsilanes would have potential to be the novel type of alkenylmetal compounds in organic synthesis as we demonstrated in the construction of stereodefined exocyclic tetrasubstituted alkene.

  The stereo-defined (E)- and (Z)-dienediyne systems related to neocarzinostatin chromophore (1) could be prepared by the coupling reaction of (E)- and (Z)-enol triflates with optically active acetylynes hearing the correct absolute stereochemistries as found in 1. Comparison of cytotoxic level of the (E)- and (Z)-dienediyne diols (32 and 33) revealed that the stereochemistry of exo-trisubstituted double bond might have a posibility to control the cytotoxicity of the acyclic analogues related to I.

  Ring cleavage and reconstruction via intramolecular aldol condensation followed by Grob fragmentation under acetalization conditions (BF3/ethylene glycol) was developed into a novel ring cleavage based on intermolecular aldol condensation. On the basis of this reaction, (R,R)-3,5-dimethylcyclohexanone was converted into the chiral straight-chain compound with syndiotactic methyl function. The ring
