β¦ Synopsis
There are only few papers in the literature dealing with the reaction oi 3-carens with formaldehyde. I-4 Without catalysts this reaction yields 3-hydroxymethyl-4-carene /IV/ as main product together rith small amount oi 3-hydroxymethyl-4/10/-carene /II/.
Studying the reaction oi 3-carene with iormaldehyde in anhydrous aoetic acid we found that two additional products were also formed: the dlacatate oi 3-hydroxymethylcaranol-4 /I/ and the bicyclic ether 2,24lmethyl-6_rethylene-3-oxabicyclo-[3.3.1.]-nonane /III/.5 \ P + CB20 ' IV x Part VI: Rocznlkl Chem.
