protecting group strategy for carboxylicacids is expanded. Thermosensitive esters are readily prepared using a known procedure, and their stability under neutral condition is investigated. Effective thermolytic deprotection initiated only by temperature for different carboxylicacids is demonstrated, and the compatibility of a thermolytic protecting group with acidic and basic protecting groups in an orthogonal
