Facile (Triazolyl)methylation of MACOS-derived Benzofused Sultams Utilizing ROMP-derived OTP Reagents
摘要:
A combination of MACOS scale-out and ROMP-derived oligomeric triazole phosphates (OTPn) have been successfully utilized for the preparation of a 106-member library of triazole containing benzothiaoxazepine-1,1-dioxides. This report demonstrates the utilization of a suite of soluble OTPn reagents for facile (triazolyl)methylation of 10 MACOS-derived sultam scaffolds in purification-free process for parallel synthesis of small molecule collections for HTS.

Go with the flow! Using a combination of continuous‐flow techniques and microwave irradiation, a 19‐member collection of 5–10 gram quantities of benzthiaoxazepine‐1,1‐dioxides has been produced (see scheme). The elimination of intermediate‐ and large‐scale process optimization by invoking the concept of scale‐out (rather than scale up) has significantly reduced the time necessary to prepare these compounds
