This chiral isothiourea homobenzotetramisole ((R)-HBTM) developed by the Birman lab is an organocatalyst that has been used for kinetic resolution, determination of absolute configuration, and nucleophile-catalysed, Michael–aldol-b-lactonization (NCMAL). This same product was previously listed as L511730, and the complementary (S)-HBTM organocatalyst (900542) is also available.

The Journal of organic chemistry, 81(15), 6253-6265 (2016-07-15)
Two different protocols were developed and optimized to address the need for (1) high sensitivity or (2) convenient utilization in the determination of the absolute configuration of secondary alcohols. The first protocol uses the competing enantioselective conversion (CEC) method to
The Journal of organic chemistry, 78(12), 6291-6296 (2013-05-22)
A concise approach to the synthesis of homobenzotetramisole and derivatives is described. Our strategy features a one-pot acylation-cyclization of 2-aminobenzothiazole with α,β-unsaturated acid chlorides to afford annulated pyrimidones. Subsequent Grignard addition followed by acid-promoted dehydration and reduction provides good overall

A novel, reagent-free catalytic transformation of α,β-unsaturated thioesters into 2-substituted thiochromenes has been developed, with carbon dioxide as the only byproduct. Amidine-based catalysts, particularly homobenzotetramisole and its analogues, achieve high enantioselectivities and yields in this process.

A new method was developed to assign the absolute configuration of molecules using kinetic resolution catalysts. Secondary alcohols were acylated in the presence of Birman's S-HBTM and R-HBTM catalysts, and the fast-reacting catalyst was identified by NMR analysis of the
Organic letters, 15(3), 472-475 (2013-01-18)
A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined. An
