✦ Synopsis
Novel reagents, bis(l-methoxy-2-methyl-l-propenyloxy)silanes (2a-d) have been shown to be very useful bifunctional protecting agents for various types of H-acidic materials, such as diols, dithiols, diacids and their combined materials. The reaction proceeds rapidly under mild conditions to give the
