Total synthesis of (-)-dactylynes

The first total synthesis of (-)-dactylyne (1) and (-)-isodactylyne (2), which have been isolated from sea hare, is described in detail. Critical steps in the synthesis include a stereoselective construction as well as an intramolecular ring closure of 32, and the effective double elongation reactions (59 → 63 and 64, 67 → 68, and 70 → 71).

Highly Regioselective Ring Opening of 2,3-Epoxy Alcohol Methanesulfonates

Reaction of 2,3-epoxy-1-ol methanesulfonates with diethylaluminum chloride or with the mixture of diethylaluminum chloride and diethylamine hydrobromide in dichloromethane gave rise to regioselectively the corresponding 3-chloro- and 3-bromo-1,2-diol 1-methanesulfonates, respectively, in excellent yields.
