Chem. , 47 : 4362 Yield of the dithiane carbometnoxylation was relatively low (45%, after distillation) and a viscous residue was always recovered from the distillation pot. Although not examined, but to the light of a recent publication) this product might be a dimer such as 8. To prevent formation of 8, the authors recommended “inverse addition” i. e. addition of the lithio-dithiane into methyl chloroformate at −78°C. We didn't experiment this technique as this part of our work was done prior to this publication.
