Phenylboronic acid VOLUME

The condensation of a, 3-unsaturated carbonyl compounds with phenols is a well-established method for the preparation of 277-chromenes and is reviewed in the preceding volumes <1984CHEC, 1996CHEC-II>. Phenylboronic acid can effectively mediate this condensation <1998S279>. C(3)-Symmetrical 2/7-chromenes are synthesized using a phenylboronic acid-mediated triple condensation of phloroglucinol 53 with three equivalents of an a,(3-unsaturated carbonyl compound (Equation 28) <20050L467>. [Pg.439]

The increase in production volume of the phenylboronic acid process using a microflow system has been studied. At the laboratory stage, a throughput of lOL/h is achieved using a minimixer, enabling the... [Pg.218]
