Synthesis of analogues of linckoside B, a new neuritogenic steroid glycoside

A facile synthetic approach toward six designed analogues (2-7) of linckoside B, a new neuritogenic steroid glycoside isolated from the Okinawan starfish Linckia laevigata, has been developed. The key steroid aglycon was achieved by a dimethylaluminum chloride-mediated 'ene' reaction. A versatile strategy was employed for the construction of glycosidic bonds through Schmidt's procedure using a glycosyl trichloroacetimidate donor.

Stereocontrolled synthesis of contignasterol's side chain

The four models of the contignasterol's side chains (2-5) have been stereospecifically prepared. The key reaction in the synthesis is a dimethylaluminum chloride-mediated 'ene' reaction between the steroid derivative 6 and the pseudo-enantiomeric aldehydes 7 and 8.

THE TOTAL SYNTHESIS OF THE WATER MOLD SEX HORMONE OOGONIOL

The water mold sex hormone oogoniol (1a) has been synthesized from adrenosterone in 18 steps in 7.0percent overall yield.The crucial step introduces the stereochemistry at C-15 and C-20 through a highly efficient 1,4-addition of the organocyanocuprate gen
