Organocatalytic asymmetric synthesis of 5-(trialkylsilyl)cyclohex-2-enones and the transformation into useful building blocks

(Chemical Equation Presented) A simple organocatalytic approach to highly attractive chiral building blocks is presented. By the reaction of β-ketoesters with αβ-unsaturated aldehydes using a chiral IMS-protected prolinol as the catalyst, optically active 5-(trialkylsilyl) cyclohex-2-enones are formed in good yields and with 98-99% ee. The applications of 5-(trialkylsilyl)cyclohex-2-enones for the formation of 5-(hydroxy)cyclohex- 2-enones and the A-ring of 19-nor-1α,25-dihydroxyvitamin D3 are also presented.

Cyclic Olefins by Anodic Oxidation of β-(Trimethylsilyl)carboxylic Acids. - β-(Trimethylsilyl)acrylic Acid Derivatives as Acetylene Equivalents in Diels-Alder Reactions

Trimethylsilyl-substituted dienophiles 1, 2, and 4 react with dienes 6-14 in 66-100percent yields to give β-trimethylsilyl-substituted carboxylic acids 15-25, some of which are hydrogenated to 26-31.These are decarboxylated-desilylated to cyclic olefins 35-47 by Non-Kolbe electrolysis in 45-91percent yields.The dienophiles 1, 2, and 4 are thus suitable acetylene equivalents for Diels-Alder reactions.
