Going from -3.7V to -32V to is a boost, a negative boost.

To make things more less confusing, here's are application notes Designing a negative boost converter from a standard positive buck converter and Positive Buck Regulator Makes Negative Boost DC/DC Converter. (The regulators in these app notes are intended to be positive bucks, but repurposed as negative boosts.)

For a simple inductive boost converter, it's advisable not to have a boost factor greater than 6. This applies to both positive and negative boost.

p.s. We’re situated roughly in the same neck of the woods, interestingly.
