Dear Paolo,
there is the case of Mir Mahmud (d. 1689), a Sufi master of the Ni'matullahi order who migrated from Iraq to the Hyderabad in the Deccan and to which alchemical knowledge is attributed in hagiographical sources. On Mir Mahmud you can check my articles which however do not focus on alchemy:
“À propos du renouveau ni‘matullāhī. Le centre de Hyderabad au cours de la première modernité”, Studia Iranica, 42, 2013, p. 91-118.
« The mujaddid and the majdhūb. Shāh ‘Alī Riḍā (d. 1215/1801) and the Different Narratives of the Ni‘mat Allāhī Renewal », in Denis Hermann – Mathieu Terrier, eds., Shi‘i Sufism in Modern Times, London, I. B. Tauris – Institute of Ismaili Studies, 2020, pp. 157-174.
I also mention several Sufis expert in alchemy who however were Indian Muslims, in my work Soufisme, religion et médecine en Islam indien. Paris, Karthala, 2010.
All the best,
Fabrizio
