Development of a Telescoped Flow Process for the Safe and Effective Generation of Propargylic Amines. MOLECULES (BASEL, SWITZERLAND) 2019; 24:molecules24203658. [PMID: 31658759 PMCID: PMC6833020 DOI: 10.3390/molecules24203658] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Revised: 10/07/2019] [Accepted: 10/08/2019] [Indexed: 12/28/2022]
Abstract
Propargylic amines are important multifunctional building blocks that are frequently exploited in the synthesis of privileged heterocyclic entities. Herein we report on a novel flow process that achieves the safe and effective on-demand synthesis of propargylic amines in a telescoped manner. This process minimizes exposure to hazardous azide intermediates and renders a streamlined route into these building blocks. The value of this approach is demonstrated by the rapid generation of a small selection of drug-like thiazolines that result from a high-yielding reaction cascade between propargylic amines with different aryl isothiocyanates.
