, more than 60 synthetic routes have been developed to date, however, most of the synthetic routes utilise the potentially hazardous azidechemistry making them not green, thus not amenable to easy scale up. Consequently, this study exclusively demonstrated safe and efficient handling of potentially
explosive azidechemistry involved in a proposed Tamiflu route by taking advantage of the continuous-flow technology. The azide intermediates were safely synthesised in full conversions and >89% isolated yields.

have been developed towards Tamiflu to date [1][2][3]. However, most of these synthetic approaches suffer from the use of potentially hazardous azidechemistry, thus raising safety concerns [4] and eventually ruled out for large scale synthesis in batch systems [1][2].
