Abstract This paper reports the synthesis of several 11,14-dimethoxydeoxypodocarpic acid derivatives from (+)-podocarpic acid. The synthesis of the naturally occurring sesquiterpene, (+)-winterin, from Drimys winteri illustrates a synthetic application of the 11,14-dimethoxy intermediates and establishes the absolute configuration for winterin.

Genecological variation of two contiguous populations of Drimys winteri (Forst.)
1996En la precordillera andina de Parral se encontraron dos poblaciones contiguas de canelo (Drimys winteri Forst.), las que eran claramente diferentes a simple vista y que ocupaban hábitats distintos. Debido a esto surgió la interrogante acerca de su taxonomía y se planteó la hipótesis de una posible diferenciación genecológica entre ambas poblaciones ...

A set of 17 permanent plots of a Drimys winteri young second growth forest were established in two adjacent sectors of the Coastal Range of Valdivia, during 1985. They were intervened in summer 1986, applying 5 thinning treatments, randomly assigned to the sample units. The evaluation comprised four vegetative periods, from 1986 to 1990.

Mixed-effects height-diameter models for Drimys winteri in the south (41-43° S) of Chile
2019Drimys winteri is an abundant tree species in the natural forests of Chile, growing as secondary forest of high ecological and economical importance between 41° and 43° S. The height-diameter relationship is key for estimating volume, biomass and for understanding ecological features of tree species.

Young secondary forests of Drimys winteri have excellent growth and regeneration, and cover an area of 230,000 hectares in Chile. However, there is no supply of high-value timber to feed the growing market opportunities. The objective of this study was to evaluate the profitability of thinning trials in secondary forests of Drymis winteri in a medium ...

The plant cuticle plays important roles in organ development and adaptation to stresses. Cuticular waxes are mixtures of very-long-chain fatty acid derivatives, also comprising cyclic compounds. The biosynthesis of the common wax constituents and specialty compounds occurring in some plant species has been researched. However, little is known about how
