摘要: Abstract A number of optically active cyclic ketones derived from (−)-umbellulone were prepared, and their UV absorption NMR spectra ORD curves measured. The sign the Cotton effect associated with n - π * transition CO group for each ketone is related to its configuration preferred conformation.
