Kp. Volcho et al., NEW POSSIBILITIES OF ISOPRENOIDS CHEMISTRY WHEN USING A HETEROGENEOUSCATALYST - ASKANITE-BENTONITE CLAY, Journal of molecular catalysis. A, Chemical, 125(2-3), 1997, pp. 85-86
We showed that new heterocyclization reactions resulting in the compou
nds of a unique structure and a potential biological activity proceed
when hydroxyolefins of menthane and carane series are allowed to react
with salicylaldehyde 1 on askanite-bentonite clay at room temperature
. Slight changes in isoprenoid structure yield significantly different
reaction products. (C) 1997 Elsevier Science B.V.
