Unfolding the frontalin chemistry: a facile selective hydrogenation of 7-methylidene-6,8-dioxabicyclo[3.2.1]octanes, 2:2 ensembles of ketones and acetylene
Abstract:
Nickel-catalyzed low pressure hydrogenation of 1,5-diaryl-7-methylidene-6,8-dioxabicyclo[3.2.1]octanes proceeds chemo-specifically at the double bond and brings about mostly 1R*,3R*,5S*,7R* diastereomers.
