Asymmetric approach toward chiral cyclohex-2-enones from anisoles via an enantioselective isomerization by a new chiral diamine catalyst

A 3-step asymmetric approach toward the optically active chiral cyclohex-2-enones from anisoles has been developed. The crucial asymmetric induction step is an unprecedented catalytic enantioselective isomerization of β,γ-unsaturated cyclohex-3-en-1-ones

Enantiospecific total synthesis of (-)-bakkenolide III and formal total synthesis of (-)-bakkenolides B, C, H, L, V, and X

A concise enantiospecific synthesis of (-)-bakkenolide III was accomplished from (S)-(+)-carvone. The key step involved radical cyclization of an iodoketone intermediate which afforded the cis-hydrindanone skeleton. Further synthetic transformations generated bakkenolide III, which also constitutes the formal total synthesis of (-)-bakkenolides, B, C, H, L, V, and X.

Chemical synthons and intermediates

The invention provides novel six and seven-carbon termini-differentiated polypropionate stereotetrads and stereopentads useful in syntheses of natural products. The invention also provides a novel alkylative sulfenylation-desulfonylation process that efficiently transforms enantiopure epoxyvinyl sulfones to syn and anti dienylsulfides in two operations.

Syntheses of highly substituted enantiopure C6 and C7 enones

Enantiopure epoxyvinyl sulfones SS-9a, SS-9b, produced from Jacobsen epoxidation of 2-phenylsulfonyl 1,3-cyclohexa- and cycloheptadiene, are used as a template for the construction of substituted cycloalkenones and as chiral synthetic equivalents of enone
