Cyclic ketals and acetals of norbornane carboxyaldehyde
Abstract
Abstract CHEMICAL COMPOUNDS CHARACTERIZED BY THE STRUCTURAL FORMULA 1-R4,2-R3,2-((-O-R6-O-)>C(-R5)-),3-R1,3-R2-NORBORNANE WHEREIN R1, R2, R3 AND R4 EACH REPRESENTS HYDROGEN OR METHYL, R5 REPRESENTS HYDROGEN OR LOWER ALKYL AND R6 REPRESENTS A POLYMETHYLENE RADICAL OF FROM 2 TO 4 CARBON ATOMS WHICH IS UNSUBSTITUTED OR SUBSTITUTED WITH LOWER ALKYL GROUPS HAVE VERY PLESANT, STRONG AND LONG LASTING AROMAS AND ARE ARE USEFUL AS COMPONENTS IN FRAGRANCE COMPOSITIONS. THESE COMPOUNDS CAN BE PREPARED BY AN ACETALIZATION REACTION OF AN APPROPRIATE NORBORNANE OR NORBORNENE CARBOXALDEHYDE OR AN APPROPRIATE NORBORNYL OR NORBORNENYL ALKYL KETONE WITH A DIHYDRIC ALCOHOL. THE NOVEL CHEMICAL COMPOUNDS CHARACTERIZED BY THE STRUCTURAL FORMULA 1-R4,2-R3,2-((-O-R6-O-)>C(-R5)-),3-R1,3-R2-NORBORNANE WHEREIN R1, R2, R3, R4, R5 AND R6 ARE AS DEFINED ABOVE ARE PARTICULARLY PREFERRED DUE TO THEIR OUTSTANDING USEFULNESS AS AROMA CHEMICALS.
