โœฆ Synopsis

The intermediacy of a ten-membered carbocycle in the biogenesis of bicyclic sesquiterpenes originally suggested by Barton and de Mayo (1) has been brilliantly extended

A convenient route to make a-hydrazino esters from their corresponding a-amino esters is reported. A key step is selective nitrosamine reduction using activated Zn, conc. HCl, and methanol at low temperatures giving nearly quantitative yields of the pure a-hydrazino esters
