Abstract:
(-)-Ambrox, a highly prized and commercially significant component of ambergris, finds widespread application in perfumery, cigarettes, cosmetics, and the food industry. Despite considerable attention to this research area over the years, an environmentally friendly and practical method for synthesizing (-)-ambrox has remained elusive. This study presents a succinct and efficient approach to (-)-ambrox synthesis, involving two consecutive alkylations at C-6, followed by an acid-catalyzed cyclization to give bicyclic ketones starting from (R)-carvone. Subsequent reduction, Barton Vinyl Iodide synthesis, alkylation, and an acid-catalyzed cyclization collectively achieved the synthesis of (-)-ambrox with a satisfactory yield of 26.2 %.

Nucleophilic Aromatic Substitution: Addition–Elimination (SNAr)
The reaction begins with an attack of the nucleophile on the carbon that holds the leaving group. This results in the delocalization of the π electrons over the ring carbons. The resonance interaction between...

Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.
