Sodium Dithionite Reduction of 2S,5R-(−)-menthone and R-(+)-pulegone in the Presence of β-Cyclodextrin and Hydroxypropyl-β-cyclodextrin

, 2003
Menthone on reduction with sodium dithionite, showed a good amount of menthol formation in the water/DMF system, with increasing β-cyclodextrin (β-CD) concentration from 47.0% for 0.1 equivalent of β-CD to 93.5% for 1 equivalent of β-CD.

Stereoselective cathodic synthesis of 8-substituted (1R,3R,4S)-menthylamines

Beilstein Journal of Organic Chemistry, 2015
The electrochemical generation of menthylamines from the corresponding menthone oximes equipped with an additional substituent in position 8 is described. Due to 1,3-diaxial interactions a pronounced diastereoselectivity for the menthylamines is found.
