Quinone Derivative

The Diels-Alder reaction of vindoline and methyl vinyl ketone resulted in a Friedel-Crafts reaction product. In the reaction between the ortho-quinone derivative of vindoline and N-phenylmaleimide, two anomalous products were obtained, a vindoline dimer, and a condensed vindoline derivative.

Retrosynthetic Analysis

This paper reports a retrosynthetic analysis that led to the conception of a synthetic strategy for the construction of ryanodol (2). The preparation of a key diene, i.e., spirolactone dienone 47 (19 → 31 → 33 → 48 → 49 → 52 → 47), and its Diels–Alder reaction with methyl vinyl ketone are reported. Keywords: strategy, synthesis, ryanodol, diterpene.
