reactions of monoterpenoids (−)-isopulegol, (+)-neoisopulegol and (1R,2R,6S)-3-methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol 5 with aromatic and heteroaromatic aldehydes. These compounds resemble in structure phytocannabinoids, some of them demonstrated analgesic activity in vivo. Polyhydrochromenes containing amino groups were obtained through the interaction of (−)-isopulegol with 5-hydroxymethylfurfural

the monoterpenoid (–)-isopulegol and carbonyl compounds in the presence of the BF3·Et2O–H2O system, which acts as both an acid catalyst and a fluorine source. The use of the readilyavailable and easy-to-use BF3·Et2O reagent makes this method of obtaining fluorinederivatives simple and practical.

A series of new compounds with hydrogenated 2H-chromene framework was synthesized starting from aliphatic aldehydes and available p-menthane monoterpenoid (−)-isopulegol in the presence of montmorillonite K10. These compounds were formed as a pair of diastereoisomers, which were isolated individually using column chromatography. Some of the compounds obtained were found to exhibit high analgesic activity in in vivo tests.
(R)-Citronellal undergoes initial ene reaction followed by Prins cyclization with aldehydes in the presence of 5 mol % of scandium triflate at ambient temperature to furnish octahydro-2H-chromen-4-ols in good yields and with high cis-selectivity. The use of scandium triflate makes this procedure simple, more convenient, and practical. (C) 2010 Elsevier Ltd. All rights reserved.
