derivatives 5 produces 2,6-dioxabicyclo[3.1.0]hexanes 6; the mechanism is postulated to involve a hydroxyl-triggered [3.3]-sigmatropic allylrearrangement. As the same catalysis is extensible to their tertiary alcohol analogues 7, distinct dihydrofuranyl alcohols 8 were obtained through a [3.3]-allyl rearrangement that is not assisted by the hydroxyl group.
The present invention relates to a compound of general formula I
Wherein R1-7, Hy, and X are as defined in claim 1. Such compound of formula I binds to VDAC1 and is suitable for use in a method for treating diabetes or pre-diabetes in a subject in need thereof.

generality of Lewis base catalyzed, Lewisacidmediated, enantioselective vinylogous aldol additionreactions has been investigated. The combination of silicon tetrachloride and chiral phosphoramides is a competent catalyst for highlyselectiveadditions of a variety of α,β-unsaturated ketone-, 1,3-diketone-, and α,β-unsaturated amide-derived dienolates to aldehydes. These reactions provided high levels
